Men's Altra Provision 4

The Provision 4 exemplifies the evolution of technical support in running shoes. It is a completely updated and overhauled version of the previous models and is at the forefront of natural biomechanical advances. In addition to a medial GuideRail, we've developed a new arch feature, unique to Altra which uses proprioception to help slow pronation and neutralize your step cycle. This feature is a new, revolutionary way of offering support only when you need it and without interrupting your natural stride. Neutral runners or those branded as "stability shoe only" wearers will both love this fresh approach to guided, natural foot movement.

Benefits Include:

• Innovative, lightweight support shoe

• New dynamic arch feature for enhanced guidance

• GuideRail for extra medial support
