Very comfortable, right out of the box. I saw someone complaining about the part of the shoe where the laces actually attach inside the shoe to flaps that run along the ankle and attach to the insole. No problem for me. I think this might be what makes the shoe feel so snug, stable, comfortable. Great for my workout or just walking around town. I'd say it runs a bit small, but not a lot. If the size you normally order fits without any room for error, you might want to go up a half size on this shoe.
