At first this felt a bit snug, but after a day the shoe seemed to form around my foot like a glove.
Another feature that took a day or two to get use to was the roller effect of the shoe's sole - there is tremendous support and cushioning in there, and it is fantastic, but it takes a little getting used to.  After a few more days, the shoes felt like padded slippers, they are simply amazing in construction, comfort, support,  and style to me.  I love them!
