Initially I didn't think these were very comfortable but I put them on at work (they shipped to my office) and after a day or so wearing them they felt much better. I think that is because they kind of shape to your foot a bit and that is what I expected when they weren't comfortable at first. It's not that they were uncomfortable really, but I had an old pair by another brand and they are very worn but still really comfortable, just dirty, so going from those to this new pair required a transition period. Now I wear them daily and I really like them. They fit snuggle enough that I don't accidentally walk out of them but they are not tight and they don't rub. They do make my feet perspire a little sometimes, top and bottom, but I get that in my other brand too and I think it's too be expected with this kind of material. Most of the time my feet are fine.<br /><br />These are not super cushy like some I've worn, but they are pretty comfortable overall. Time till tell how they hold up.
