Unleash your natural instincts.

Satisfy your long-distance running impulses with the natural feel and lightweight, yet stable design of the Altra Women's Impulse Running Shoe. The Zero Drop platform encourages a more natural, low-impact strike that properly aligns body posture and strengthens lower leg muscles. And unlike the narrow toe boxes of most running shoes, its Footshape toe box allows room for your toes to spread out to enhance comfort and balance.

The friction-free, lightweight, and breathable upper prevents hot spots and improves comfort. A responsive, high-rebound EVA and A-Bound blend midsole cushions your every step and propels you into your next stride. Varus Stability Wedge Technology provides flexible stability to prevent early and late-stage foot collapse, and Stabilipod technology acts as a stabilizing tripod to prevent over-pronation. It's finished off with a lightweight FootPod outsole that maps the tendons and bones of your foot to provide a natural, easy flex that allows your foot to move naturally.

  • Zero drop platform

Fabulous Fit

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: Runs small

Designed to be snug, as they run small, but has a wonderful toe box, very spacious. Definitely a neutral fit as well, so if you pronate or supinate make sure to add an insert. It is also designed for a mid-strike, keep that in mind if you love running heel-to-toe, may just take some time to adjust but will be well worth it! Absolutely love this shoe!

Ugly but fun.

The Altra Impulse are a terrific zero-drop shoe, with enough cushioning to be comfortable on longer runs. The wide toe box allows my toes to splay naturally, which makes running so much more pleasant. I also love the off-set lacing pattern, because it reduces the amount of pressure on my arches, which are really high. I ordered a half size larger than my normal running shoe size, because other reviewers have said that they run small, and that was a good choice, because they fit perfect. So far I am impressed, wish it came in more colors.

Ugly but fun.
