Underfoot, the Tribase Reign 4 brings updated midsole and outsole technology to deliver exceptional traction across technical terrain along with responsive cushioning mile after mile. I’ve found this trail running shoe’s dual-compound construction ideal for maintaining pace and confidence over roots, rocks, and everything in between.
Starting from the ground up, the aggressive multidirectional lug pattern on the Reign 4’s outsole takes bite after bite across variable trail surfaces. Compared to the previous Reign 3 model, the lugs on the Reign 4 wrap higher up the toe bumper and feature a slightly more prominent heel crash pad for downhill control. The lug material also seems a bit stickier for maintaining grip on wet roots and mud.
On a recent Sunday long run across the rocky trails near SNP in Virginia, I felt like a mountain goat bounding uphill and bombing down loose declines with equal control. The Reign 4’s outsole lugs maintained secure traction even across wet creek crossings and loose scree. Where other trail shoes often slip, the Reign 4 just keeps clawing ahead.
The EVA foam midsole provides cushioned stability underfoot mile after mile. Under the rearfoot, UA’s proprietary TriBase technology utilizes a firmer compound for lively energy return and forward propulsion. Up front, softer EVA foam absorbs shock while allowing the forefoot to splay naturally on uneven terrain.
Compared to the dense compressed midsole of the Salomon Sense Ride 4, the Reign 4 felt softer on first step-in yet firmed up nicely at pace with no instability or mushiness. Those long Sunday miles flew by with my feet and legs staying remarkably fresh late into the run.
On steep rooty uphills, the Reign 4’s balanced cushioning keeps feet protected and transitions quick from strike to toe-off. Bombing downhill, the firmer heel foam prevents jarring while the grippy lugs handle like trail bike tires carving around loose switchbacks.
For optimal traction across roots, rocks, and everything between, the updated outsole and balanced midsole of the Tribase Reign 4 is purpose-built for variable mountain terrain. This versatile trail shoe has quickly become my go-to for long mountain runs where footing and responsiveness are paramount.

Trail running shoes must balance sturdy protection and support with ventilation and flexibility to keep feet powered mile after mile. The Tribase Reign 4’s engineered mesh upper achieves this ideal blend for comfort across long mountain runs.
Weighing in at just over 10 oz in a men’s size 9, the Reign 4 provides a lightweight feel compared to bulkier traditional trail shoes. The streamlined upper lacks any superfluous overlays or stabilizing straps. Yet the breathable mesh still delivers security and foothold when pushing pace over uneven terrain thanks to Strategic reinforcements.
Across the midfoot, denser mesh incorporates printed welded overlays for structure and support when cinching down the laces. The burly toe bumper takes on frontal impacts while guarding against premature wear. Underneath, a flexible yet protective rock plate absorbs harsh rock strikes.
While rugged, the Reign 4 still fosters air flow and ventilation for comfort in warm conditions. The lightweight mesh along the forefoot and tongue allows hot air and vapor to escape. My feet stayed remarkably cool and dry on a recent humid Appalachian trail run.
Inside the shoe, a partial ankle sleeve secures the heel and connects to the gusseted padded tongue. This integrated interior construction eliminates irritation and hot spots while locking down the midfoot. My feet experienced no slippage or discomfort even bombing down rocky declines.
For technical trail running across long distances, the Tribase Reign 4 perfectly balances sturdy support with strategic flexibility and ventilation. The rugged yet breathable upper provides just enough security without overdoing structure and bulk.
After hundreds of mountain miles, the Reign 4 still looks and performs like new thanks to the abrasion-resistant mesh and well-placed protective reinforcements. Ready for any distance or terrain, this strategically constructed upper exceeds demands from roots to rugged ridges.
Note the secure lace-up closure and padded tongue/collar for comfort and lockdown
Dialing in a secure midfoot lockdown is crucial for confident trail running across variable terrain. The Reign 4’s integrated lacing system and interior padding work together to eliminate in-shoe movement while preventing irritation.
The asymmetric lacing design provides customizable cinching from toe to ankle. I found I could really crank down through the first few lower eyelets to lock my heel securely in place without creating pressure points across the instep.
An extra eyelet pair at midfoot lets you fine tune fit for your foot shape. On steep descents, I can lace the midfoot tightly without constricting toe splay. The thin yet durable laces remained tied even through muddy scree fields and creek crossings.
Inside the shoe, a plush padded tongue separates the foot from lace pressure. Underneath, a partial bootie sleeve integrates the tongue along the medial midfoot to prevent sliding. My feet experienced no slippage even pounding downhill with a fully loaded hydration vest.
Around the collar, ample foam padding prevents any heel lift while eliminating rigid points that could lead to blisters. After multiple 20+ mile runs, I’ve experienced zero hot spots or rubbing at the ankle.
On the trails, you need to trust your shoes will hold tight from first step to last. The Reign 4’s secure lacing system and interior construction instill confidence to charge ahead across roots and rocks without second guessing your footing.
Between the customizable lace-up closure and integrated interior sleeve, Under Armour hit the mark with lockdown and comfort. From mellow nature walks to bombing down mountain descents, my feet stay locked in and irritation-free within the Reign 4.
Describe the minimal yet efficient geometry for agility on trails
Navigating rocky, rooty trails demands agile footwork and quick turnover. The Tribase Reign 4 provides an athletic platform to attack technical terrain yet retains enough cushioning for all-day comfort.
With a flexible forefoot and medium 6mm offset, the Reign 4 encourages a natural running gait. The smooth rocker geometry facilitates transition from initial contact to toe-off when climbing rooty inclines or bounding over obstacles.
Underfoot, the early stage Meta-Rocker design promotes momentum as you roll through each step. Compared to the rigid unsupported forefoot of the Saucony Peregrine 11, the Reign 4 provides a more natural ride across uneven terrain.
The modest 24mm/18mm stack height puts you closer to the ground for terrain feedback and responsiveness. Still, ample cushioning takes the edge off rocks and roots to prevent jarring and fatigue. On 20+ mile runs, my legs still feel relatively fresh late into each outing.
An integrated yet flexible rock plate provides underfoot protection without deadening road feel or flex. The smooth transition encourages rhythm and flow from downhill bounding to uphill scrambling.
Weighing 10.2 oz in a men’s size 9, the Reign 4 provides a lightweight platform ready to pick up the pace. The responsive foam and dialed geometry make easy work of technical trail obstacles.
For taking on roots, rocks, and uneven terrain at speed, the Tribase Reign 4 sets the benchmark. The efficient ride fosters agility mile after mile over variable topography to help you reign over the most rugged trails.
Explain the multi-surface lugs designed for grip on varied terrain
Trail runners need confidence their shoes can handle whatever terrain comes next, from loose dirt to muddy slopes. The Reign 4’s multi-directional outsole lug design maintains stability across all surfaces.
Unlike road runners with simple horizontal traction patterns, the Reign 4 incorporates aggressive lugs of differing shapes/depths that wrap around the perimeter. Holding an older Reign 3 beside the latest model, you can see the evolution towards an even more pronounced outsole configuration.
Around the lateral heel, triangular lugs of varying size provide bite on steep uphills and confidence edging downhill. Up front, chevron lugs point forward for clawing uphill while also facilitating forefoot flex.
The prominent lugs extend up the front toe bumper, allowing you to dig in when cresting steep pitches. Under the arch, additional wraparound traction maintains stability when traversing sideways across sloped terrain.
I’ve tested the Reign 4 across the muddy, rocky trails of Virginia, slick roots in Vermont, and loose desert terrain around Las Vegas. The adaptable lugs deliver consistent grip no matter the surface – wet or dry.
During a foggy 10 miler in the Blue Ridge mountains, the Reign 4 traction inspired confidence bounding between rocky outcrops, soggy creek crossings, and forested switchbacks. The lugs shed muck quickly to maintain consistent footing.
From rooty singletrack to sandy washes, the Reign 4’s multi-directional lugs help you reign over any terrain. By tuning lug shape, size, and placement, Under Armour optimized this outsole for all environments.
Mention the durable lug rubber outsole material
Bombing down rocky trails demands durable outsoles that can withstand repeated sharp impacts. The Reign 4 utilizes hardy rubber compounds to maintain traction mile after mile.
The high-abrasion rubber lug material takes on the most challenging mountain terrain without rapid breakdown. After my first 50-60 miles on various Virginia trails, I inspected the outsoles to find barely any visible wear.
The durable construction means the pronounced lugs should maintain grip and integrity for hundreds of miles. Under Armour seems to have created an optimal balance of stickiness and resilience.
I’ve put the Reign 4 through the ringer on rugged Appalachian terrain riddled with jagged rocks. Compared to the Salmon Sense Ride 3 that showed significant lug tearing after similar mileage, the Reign 4 is standing up impressively.
The sticky rubber continues to provide consistent traction even as the miles tally up. I’ve been pleasantly surprised by how well the outsole has retained shape, depth, and grip even after significant time on harsh mountain routes.
Trail runners know chewing through outsole rubber is inevitable over time. But the Reign 4’s hardy lug material seems engineered for longevity across rugged environments without rapidly deteriorating.
If you’re logging big miles on rocky terrain, the durable construction and abrasion-resistant rubber of the Reign 4 inspires confidence the traction and grip won’t fade prematurely. This outsole should maintain integrity for the long haul.
Discuss the EVA midsole cushioning tuned for long miles
Responsive cushioning is crucial for logging mile after mile across rugged terrain. The Reign 4’s EVA foam midsole absorbs impact while providing energetic lift-off and stability.
Underfoot, dual-density EVA foam delivers durable yet responsive cushioning. A softer density along the forefoot dampens impact with each footstrike. In the rear, firmer foam and UA’s proprietary TriBase technology provides lively energy return for forward propulsion.
Compared to the compressed EVA in the Saucony Peregrine, the Reign 4 felt softer and bouncier at first step-in. But the foam firms up nicely at pace for stability while retaining cushioning deep into long trail runs.
Over 20+ mile mountain excursions with significant elevation change, my feet and legs stayed remarkably fresh late into each run. The Reign 4 midsole absorbed harsh rock and root strikes while providing a responsive toe-off.
The rockered profile encourages smooth rollover from impact to lift-off. An embedded yet flexible rock plate enhances protection on jagged terrain without deadening road feel.
The Reign 4 offers the elusive balance of cushioning and response trail runners need to eat up the miles. The EVA foam and rocker geometry work together to keep you running smoothly over roots, rocks, and all types of irregular terrain.
For cruising long distances across mountainous topography, the Tuned midsole of the Tribase Reign 4 helps you reign over mile after mile in complete comfort and control.
Praise the smooth ride from ground contact to toe-off
Maintaining rhythm and flow across uneven terrain keeps you efficient mile after mile on the trails. The Reign 4 provides a smooth ride from impact to push-off stride after stride.
On initial ground contact, the rockered heel promotes a natural roll forward to midfoot. The plush EVA foam softens impact while the firm UA TriBase construct prevents any heel instability or collapse.
Transitioning to push-off, the flexible forefoot and rounded toe design facilitate natural toe splay and lift. There’s no rigid “tipping point” between heel and toe.
Bounding up rocky inclines, the Reign 4 allows continuous motion without any dead spots or delayed transition. Descending switchbacks, the rocker profile and lug pattern combine to make it feel like I’m floating smoothly over irregular terrain.
Compared to other shoes like the Saucony Peregrine with a more pronounced “rocker hump”, the Reign 4 geometry fosters a consistent gait cycle from footstrike through toe-off.
The result is mile after mile of smooth striding regardless of what roots, rocks, or ruts you encounter. By tuning the sole geometry and transition points, Under Armour nailed the smooth connection from ground contact to energetic lift-off.
From steep appalachian climbs to fast flowy descents, the Reign 4 keeps each step smooth and seamless. The consistent ride helps you find rhythm and maintain efficiency anywhere the mountain trails lead.
Review the breathable mesh upper that keeps feet cool and dry
Nothing derails a long trail run faster than hot, soggy feet. The Reign 4 mesh upper provides ventilation to keep your feet feeling fresh across the miles.
Strategically placed lightweight mesh along the forefoot fosters ample airflow. The porous material allows heat and moisture to readily escape.
I’ve taken the Reign 4 on midsummer runs across Virginia’s sweltering Blue Ridge peaks. Even on 95°F days, my feet remained remarkably cool and dry throughout each outing.
The tongue incorporates perforations and moisture-wicking fabric for additional ventilation. The cushioned collar also incorporates notches to alleviate heat buildup around the ankles.
By focusing breathable mesh in sweat-prone areas, Under Armour struck the perfect balance between structure and airflow. Never do hot spots or blisters develop.
Some shoes like the Saucony Peregrine rely on excessive mesh that stretches and deforms over time. The tightly knit mesh overlaying high-wear areas on the Reign 4 ensures secure structure and foothold for the long haul.
Don’t let worries about swampy feet slow you down on summer trail runs. The Reign 4 airflow keeps your feet feeling fresh across even the most grueling miles in the heat.
Consider sizing options to get the ideal secure fit
Dialing in the right size is crucial to prevent in-shoe movement that can lead to hot spots and blisters on long trail runs. The Reign 4 offers a secure performance fit in multiple size options.
I found the Reign 4 runs true-to-size through the midfoot and heel but with a roomy forefoot to allow natural toe splay. For my narrower feet, sizing down a half-size provided a precise foothold.
With an integrated sleeve construction, be sure to try true-to-size initially. But don’t be afraid to size down if you notice excess room up front after a few test jogs. The ample toe box accommodates swelling on long runs.
Compared to the wider toebox of the Brooks Cascadia, the Reign 4 dialed in security around my midfoot without excess wiggle room up front in my typical size. The partial sleeve integrates the tongue to prevent lateral slippage.
Since feet swell on long mountain runs, a secure midfoot lockdown is vital. The Reign 4’s integrated lacing system and partial sleeve achieves that ideal blend of custom fit and accommodating room in the toebox.
Take time to test sizing to find your ideal Reign 4 fit. For narrow to average width feet, consider sizing down half a size from standard training shoes for security across uneven terrain without excess wiggle room up front.
