Run more and effort less in the women's AltraFWD Experience—Altra’s first running shoe with a 4 mm heel-to-toe drop. For runners and walkers nervous about trying one of Altra’s zero-drop shoes that have Balanced Cushioning™ in the heel and forefoot, the Experience is a great way to transition to a lower-drop shoe. The shoe’s 4 mm drop, rocker shape geometry and lightweight cushioning give you a performance-focused ride that makes daily running feel smooth and easy. Plus, the sleek mesh upper wraps your foot for all-around comfort, while Altra’s Standard FootShape™ Fit toe box lets your toes relax and spread out naturally.
