Guys who train across multiple modalities know firsthand that there’s no such thing as a one-size-fits-all shoe. For those serious about weightlifting, a pair of flat shoes to stay stable and grounded during heavy barbell work is essential for optimal performance. Runners want something lightweight with good cushioning to absorb impact and help them glide across longer distances. And for those into HIIT workouts, having a versatile pair of cross-training shoes that handles quick direction changes and conditioning-style movements is key.
For such needs, Under Armour’s UA Reign 6 exceeds expectations. For our 2026 Fitness Awards, we tested tons of cross-training shoes, and this pair stood up to the demands of HIIT training better than any other pair we tried. These cross-training shoes make unilateral movements feel noticeably more stable, while still staying flexible and supportive through the heel for quick transitions and power-driven moves. From box jumps to sprints and sled pushes, the UA Reign 6 can do it all.

Under Armour’s UA Reign 6 is built for athletes who move fast and change directions often. Its defining feature is the TriBase outsole, which promotes natural foot movement while maintaining stability through the midfoot and heel. With a very low heel-to-toe drop of roughly two millimeters, the shoe keeps you close to the ground, enhancing balance during plyometrics, lunges, and agility drills.
Weighing about 11.5 ounces, it feels noticeably nimble during high-intensity interval training and circuit-style workouts. The lightweight mesh upper enhances breathability, though it doesn’t offer as much structure for maximal lifts. While Reign 6 isn’t the best choice for heavy squatting sessions, it excels in fast-paced, sweat-heavy workouts where responsiveness and mobility matter most.
