I can honestly say I can't remember that last time I've found a shoe that was this comfortable, especially right out of the box. They required no break-in time. Little touches like the elastic in the strap at the top of the foot, and elastic in the back make the fit more flexible. Almost like a glove. I've since ordered them in 3 more colors. I wear a 12m and these are a great looking shoe. Not bulky at all.
