How the technology works

How the technology works image 1

Traditional hiking shoes can cause fatigue, ankle strain, and energy loss when you need it most. FLEXTRON acts like a springboard, boosting rebound energy as you push off, while an innovative shank delivers torsional stability for balance on uneven terrain, and high side walls secure the heel and midfoot. By reducing strain on your calves and feet, you can move more efficiently and recover faster.
