The Provision 4. This updated model exemplifies the evolution of technical support in running shoes through our revolutionary dynamic arch feature, InnovArch. This innovative feature forms a link from your head to your feet, inspiring an awareness that naturally encourages a better step cycle. Pair that with the tried and true Guide Rail technology and you’re ready to move more naturally and comfortably. Places your heel and forefoot the same distance from the ground to encourage proper, low-impact form throughout your run. Allows your toes to relax and spread out naturally for more comfort and stability. This innovative arch feature uses proprioception to establish a connection between mind, body and feet which encourages a natural foot placement in each step. Grid-like grooves in the midsole allow your foot to flex while being lighter, for more speed and better performance. An outsole technology that actually maps the bones and tendons of your foot to help it bend and move naturally. A feature found on our dynamic support shoes that acts like a highway guide rail to provide guidance only when you need it.
