I've had these about a week and so far they're wicked comfy. The sizing is a little funky. I usually wear a 10-1/2, 11 and I have these in a 10-1/2 and they're a touch too big still. I wish they had a 10-1/4. The 10 is wayyy too small. My feet are a bit on the wide side and these in a 10 are too narrow. Do yourself a favor and find these in a store and try them on and then come back here and buy the right ones.
I'm super happy with the ones I have though and will most likely be buying another pair.
