Hi - hope you don't mind my asking. I just bought them in 45.5 but usually take a 46. However, tried the 46's in store and my feet were sliding around in them as I walked. However, with the 45.5's it's much as you described. Standing still, they are fine. Snug but with some room to wiggle toes. Walking though, my big toe presses against the top-side of the shoe and with any other shoe, I'd not consider keeping them as it flies in the face of everything I've learned about buying shoes. Fingers width at the front etc.Just wanted to chime in with my fit experience on the Michaels. I bought a 44.5 last year and probably would have returned them for being too snug if I hadn't already tried the 45 around the house for a day and found them too loose. When I'm standing still, my big toe just barely touches the front of the shoe. When you are walking around in them it feels like your feet are going to be in immense pain within an hour, but I swear I've worn these things all over town, biked in them, and they are indeed comfortable. But yes, there is zero stretch length-wise. If they feel genuinely tight, size up.
However, I've read in several places that this is actually what the fit of the Michael is supposed tobe like and they 'mould to your feet' etc and in a few days/weeks they will be the most comfortable shoes known to man. Is this consistent with your experience?
