Altra Women's VIA Olympus 2

I have hallux rigidus and had to have pretty intense double foot surgery to grind down some bone spurs. I couldn't walk for a couple of months afterwards and had to wear surgical sandals, but once I could, my surgeon only let me wear these. I already tore through a pair in the last six months - they are honestly incredible. What I need specifically are as close to "zero drop" as possible (these have a 2-3 mm drop), a gigantic toe box, and a rocker bottom. It's so hard to find all three! These are it!
