This is 4 pair of Clarks I've purchase. I usually buy the white and I did, just this time I added this brown. It seems to be just a little snugger than the white ones. A size up might be an idea. I kept these as I think they will stretch a bit. The white one fits perfectly, I'm sure it is the nubuck material that is stiffer that the white leather. I still think I will enjoy them with jeans and color matching clothing. I wear very thin foot socks with these shoes.
