What size recommendation would you like to make for the model?
Buy one size smaller.
“the lotus is everything I dreamed it would be. I can hardly stand to take them off. My only complaint is that i think they are a little long and wish I'd bought a size 8 instead of 9 so i could wear them barefoot and still have warm toes. . As is, they only feel "part of my feet" if I'm also wearing a thickish sock. They actually fit a friend of mine with womens' size 10 perfectly. But I'm not sending them back because they are warm and I now can't do without them!”
