Every Altra running shoe features a fully cushioned Zero Drop™ platform that places the heel and forefoot at the same distance from the ground. This natural balance aligns the feet, back and body posture for less impact. It also strengthens the Achilles and lower calf muscles that have been weakened over a lifetime of running on elevated heels.

Promotes proper form to reduce initial impact by 3–5 times
Natural Achilles loading for better propulsion
1-to-1 ratio naturally aligns feet, back and body posture

Weight-balanced from front to back
Traditional running shoes feature pointy toe boxes that squeeze the toes out of their natural position —increasing risk of bunions, hammertoes and plantar fasciitis. Altra's FootShape™ toe box allows the toes to relax and spread out naturally and the big toe to remain in a straight position. This enhances stability and creates a powerful toe-off to maximize running performance. We wish we could call it some scientific breakthrough, but we're simply giving your foot the working space it needs.
