The Men's Provision 2. 0 Running Shoe is designed to alleviate post run pain for runners in need of pronation correction and added support for fallen arches. Innovative StabiliPod technology delivers a tripod of stability by boosting support in the medial, lateral, and heel of your foot, while the built in stability wedge slopes down from the medial to lateral sides of the foot to provide extra support and prevent excess pronation. Innerflex technology utilizes grid like flex grooves in the midsole to let your foot flex where it needs to for more speed and stability. And 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.
