The Under Armour TriBase Reign 5 offers a solid all-around training experience with excellent impact protection and stability for heavy lifting. Reviewers noted its comfortable wraparound upper and dependable grip across different surfaces. However, the actual drop is higher than advertised, and the shoe's stiffness may not suit those prioritizing flexibility for movements like planks or lunges. It's well-suited for gymgoers doing varied workouts but may not appeal to minimalist training preferences.
Full review
Low drop with unexpected measurements
The TriBase Reign 5 presents a heel-to-toe drop that differs significantly from the brand's stated specifications. While Under Armour advertises a 2mm drop, independent testing measured the actual drop at 4.8mm, which is notably higher than average training shoes. This discrepancy impacts the shoe's minimalist appeal and may disappoint athletes seeking a true zero-drop experience. The 4.8mm drop places it in the middle range among training shoes, making it less suitable for those who prefer ultra-low or minimalist footwear. The heel stack measures 22.3mm, which contributes to this elevated drop measurement and creates a more grounded feel than many competitors. This design choice prioritizes stability and control over the light, nimble sensation that some CrossFit athletes desire.
Stable platform for heavy lifting
The shoe's design excels in providing stability for weightlifting and heavy strength training. The TriBase technology features a triangular base that maximizes ground contact and promotes superior upward flexibility while maintaining grip during lifts. The heel counter is reinforced with TPU, a thick plastic that provides structure and support for serious weightlifting. This enhanced heel counter makes the shoe less flexible and more stable, which is beneficial for lifting but may reduce the articulation needed for dynamic movements. The dense Micro G foam midsole offers impact protection without compromising the shoe's stability during heavy lifting sessions.
Breathable upper with durability concerns
The upper construction uses a mesh material with reinforced areas for high-wear zones, providing a lightweight and breathable experience compared to previous models. The WARP upper offers secure fit and good volume, though some users note it can feel slightly narrow. The mesh design allows for better airflow during intense workouts, which is particularly valuable for athletes who train in warm conditions. However, the upper's durability varies, with some reviewers noting that the mesh can show wear over time, especially in high-abrasion areas. The reinforced sections help extend the shoe's lifespan, but the overall upper construction may not match the longevity of more robust materials used in competing models. The upper's performance in CrossFit environments shows mixed results, with some users praising its breathability while others express concerns about long-term wear.
Outsole traction and versatility
The TriBase outsole delivers excellent traction for various training surfaces and activities. The rubber compound provides grip suitable for lifting on different flooring types, including concrete and wood. The outsole's design includes flex grooves in the forefoot that allow for running, jumping, and skipping movements while maintaining stability during lifts. This dual functionality makes the shoe suitable for both weightlifting and high-intensity interval training. The traction performance is particularly effective for CrossFit WODs that involve multiple movements, as the outsole adapts to various ground contact points. The shoe's versatility extends to its ability to handle both static lifting and dynamic movements without compromising performance in either category.
Fit and sizing characteristics
The fit is described as true to size for those with flatter feet, though the overall width may be narrower than expected. The asymmetric lacing system provides a secure fit but can be hit or miss for some lifters and athletes. The tongue padding is thin, which may not provide sufficient comfort for extended wear. The heel counter is larger in this version, which contributes to a more structured fit that supports lifting. The collar is more comfortable with additional padding, improving overall comfort during training sessions. The fit characteristics make this shoe suitable for athletes with flatter feet but potentially problematic for those with wider feet or high arches.
Performance across training disciplines
The Reign 5 demonstrates strong performance across multiple training disciplines, making it a versatile option for athletes who engage in various activities. The shoe handles CrossFit workouts well, with the stable platform supporting heavy lifts while maintaining enough flexibility for dynamic movements. The low drop design and stable heel make it particularly suitable for functional fitness athletes who prefer a more natural foot position during training. The shoe's performance in HIIT workouts is adequate, though it may not be the optimal choice for athletes who prioritize maximum flexibility and articulation. The Micro G foam midsole provides sufficient cushioning for running portions of workouts while maintaining the stability needed for lifting. The shoe's ability to handle both weightlifting and cardio training makes it a solid choice for athletes seeking a multi-purpose training shoe.
Stiffness and articulation limitations
The shoe's midsole stiffness limits its articulation and flexibility, which may not appeal to athletes who prefer more movement freedom. The dense Micro G foam midsole, while providing excellent stability for heavy lifting, creates a stiffer platform that can feel clunky during planks, lunges, and other movements requiring foot flexibility. This stiffness is particularly noticeable for athletes who value the ability to bend and twist naturally during workouts. The shoe's design prioritizes stability over flexibility, making it less suitable for athletes who perform movements that require significant foot articulation. The midsole takes time to break in, and even after breaking in, it remains relatively rigid compared to more flexible training shoes. This characteristic may limit its appeal for athletes who prefer a more responsive, flexible platform during dynamic movements.
Strengths
- +Impressive impact protection with Micro G foam midsole
- +Extremely comfortable wraparound upper with secure fit
- +Excellent upper durability for cross-training
- +Provides stability for heavy lifting and machine workouts
- +Really nice grip on various surfaces for cross-training
Watch-outs
- −Drop is higher than stated at 4.8mm instead of 2mm
- −A bit stiff and doesn't bend easily for planks and lunges
How it compares
The Under Armour TriBase Reign 5 provides better impact protection and upper durability than the NOBULL Trainer+, but it's less flexible than the Adidas Dropset Trainer 4 and lacks the rope-climbing strength of the Nike Metcon 9. It's also heavier than the Reebok Nano X3, making it less ideal for cardio-focused workouts.
