Altra's Provision 2. 0 Men's Running Shoe is designed to improve form, efficiency, and comfort for runners who struggle with overpronation and want added support for fallen arches. Innovative StabiliPod technology delivers a tripod of stability by boosting support in the medial, lateral, and rear areas of your foot, while the built in Varus Stability Wedge slopes down from the inside to the outside of the foot to provide extra support and prevent over pronating. InnerFlex technology utilizes grid like flex grooves in the midsole to let your foot flex where it needs to for more speed and stability. Like every Altra shoe, the Provision 2. 0 features a FootShape toe box that lets your toes relax and spread out for a more comfortable, stable run and a fully cushioned Zero Drop platform that encourages natural running form and a low impact foot strike.
