FootShape™
Three fits, one philosophy.
A FootShape™ shoe isn't a wide shoe — it's a shoe with a roomy toe box and a secure midfoot. Every Altra has that signature shape, but how much room at the front and how snug through the middle varies by model. Pick the fit that matches your foot.
Fit 1 of 3
Original FootShape™
Our roomiest toe box, with plenty of space through the midfoot too. The fit for runners who want maximum room to splay and breathe — on trail, on long road, on the trail-running ultras.
Fit 2 of 3
Standard FootShape™
Roomy in the toes, secure through the midfoot. The everyday-runner fit — generous where you need space, locked-in where you need control.
Fit 3 of 3
Slim FootShape™
Roomy toes with a snug midfoot. For runners who want the FootShape benefit up front but a closer hold through the arch — typically the racing and speed-day option.
The bigger picture
Why FootShape matters at all.
FootShape is one of the two ideas Altra was built on. The other is Zero-to-Low Drop. Together they're why the shoes feel different the moment you put them on.

Want it all wide?
A handful of Altra styles come with a wide midfoot in addition to the roomy FootShape toe box — perfect if you need extra width through the arch.
