Under Armour TriBase Reign 5
Ranked #3 in Best Cross Training Shoes
Under Armour TriBase Reign 5
8 sources1 derived$125as of Aug 23

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.

Strengths
  • — Impressive impact protection with Micro G foam midsole
  • — Extremely comfortable wraparound upper with secure fit
  • — Excellent upper durability 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
