The choice of Ultra Endurance World Champion Bryan Neely.
Insoles tested by forward deployed military troops for use in military boots. "As good as, if not better, than Superf**t Gr**n. In addition to using them in my military boots, I use them in my running shoes for daily PT." - 1st Lieutenant E*****, US Army
Honeycomb gel heel cushion reduces foot and lower leg fatigue by absorbing impact shock.
Military boot insoles reduces plantar fascia strain with firm arch support.
Thermoplastic rubber support structure, with its elasticity and rubber-like material, effectively disperses impact energy away from the bone and joints, reducing impact forces.
Foot contact pad designed for temperature regulation.
Running Economy on average improved by ~8% when male endurance trained runners ran while wearing custom fit orthosis (CFO). The addition of CFO decreases vertical impact peak force (~6%) and vertical loading rate (~12%). When used in the midsole of a running shoe, thermoplastic polyurethane (TPU) produced a 4% improvement in Running Efficiency (RE), overall comfort, heel cushioning and heel cup fit and medial-lateral control).
Great for Spartan Races and pre-race training.
Deep heel cup keep your foot snug within your footwear.
