Altra Provision 4.0

The revolutionary InovArch technology is a dynamic arch phenomenon, which enhances a link from your feet to your brain to encourage your body awareness that naturally promotes a better step cycle. This promotes your natural gait in a more balanced and less stress inducing way.

The GuideRail technology is placed on the inside of the shoe. It is a triangle shape reinforcement which stabilizes your foot at the heel bone and thus limits inward movement of your knee. This way your foot is guided in a natural way. Because the GuideRail feature works only when you need it, Provision 4.0 can be worn not only by over-pronators but also by neutral runners. 

Provision 4.0 like all Altra shoes features zero drop and a foot-shaped fit. The wide toe box allows the toes to spread and keeps the toes in a straight position for better stability and a powerful toe off. The zero drop midsole keeps your heel and forefoot on the same level. This encourages your natural body alignment, improves your running technique, and helps strengthening  your lower leg muscles.
