This one is full of surprises. 

Like our brand-new supercritical midsole foam, Altra EGO™ FLO. Infused with nitrogen, it’s lightweight and responsive underfoot feel is designed to help you stay comfortable and cushioned. A low 4mm drop complements the shoe’s rocker shape geometry, designed to give the feeling of being propelled forward with each step while providing an efficient toe-off. It’s so smooth, you’ll wonder if it’s on cruise control.

We built it with an engineered spacer mesh upper, designed for breathability and a sleek look. With Altra’s signature FootShape fit, you get our roomiest toe box with plenty of room to help your toes move more freely, and space through the midfoot. So lace up, stretch out, say “ahh,” and let’s go. With this shoe, the name of the game is lightweight comfort. It doesn’t get better than that.
