Whether it's winter or summer, as soon as I walk in the door, these go right on my feet. The lining is soft and "snuggly". They keep my feet warm, but never hot and sweaty. If you're a croc fan, and you want that perfect "slipper/shoe" hybrid, you've got to try a pair of these.
I've got wide feet, and they fit perfect. Didn't have to change sizing at all.
