I bought these for my husband, his review: Very comfortable right out of the box. I know Clark has big feet, but recently I went up a half size for more comfort and a wider foot. So I wasn't sure what size to order, I also remembered that they stretch a bit compared to a pair of wallabies I had a long time ago. I usually order 11.5 in Vans without laces and have chosen 10.5 at Clark's, they are not too tight and will stretch a bit.
