One for the Road

A very light road shoe for walking, running, and training for your next hike, the Altra One 2.5 is made with speed, comfort, and stability in mind. The proprietary Zero Drop platform delivers level cushioning and ideal weight balance from heel to forefoot, while the FootShape toe box encourages natural toe splay and proper running form. To put a spring in your step, the dual-layer EVA midsole features A-Bound top layer that reduces the impact of hard surfaces. Finally, InnerFlex and FootPod technology add grid-like flex grooves and pattern mapping for a great fit.

Note: At checkout, you’ll have your choice between the Men’s shoe (in Midnight Blue or Hornet) and the Women’s shoe (in Sprite or Fuchsia Mint). Full and half sizes are available in Men’s 7–15 and Women’s 5–12.

The History of Altra

Altra was born in the back room of a Wasatch Mountains running store, where owner Golden Harper met countless runners who complained of knee pain, shin splints, and other injuries from traditional pointed toe boxes and thick, heavy heels. A competitive runner himself, Golden began experimenting with shoe alterations to solve his customers’ problems. By melting the outsoles (in his trusty toaster oven!), he was able to remove the excess heel elevation for a more natural, relaxed foot position. The new platform design was dubbed Zero Drop.
