These are enormously comfortable shoes! Just feel wonderful, and keep your feet VERY warm. You would not want to be wearing these unless it is wintertime.

Despite the suggestions of others, I ordered my normal size (mens 11) and found the shoes to fit perfectly. Ordering a size larger would have been a huge mistake.

My only complaint is that they don't stay on your feet all that well. I had hoped that the mid-rise heel would grip better, but my heel slips out when I'm walking. Not a huge problem since I don't intend on wearing these much when I'm out, but I'm regret that I didn't buy the version that has a strap on the back (the Wooly Mamnoth).

Still, happy with the shoes and looking forward (well, sort of) to the cold weather!
