I just bought these shoes a few days ago. Yesterday I wore them for a 50 min spinning session and they fit rather nicely. They were comfortable! Today I did another 50 min spinning session and 35 minutes in, my toes and balls of my feet went numb. I wear a size 10 and they felt roomie. Even as I walked around in them I could feel my heel slightly lifted so the shoes themselves were not too tight. I'll be returning these and look into another pair of cycling shoes.
