Bottom Line Recommendation: Buy these for the style factor, maybe buy these for active use, do not buy these for hard use.

I wear size 11's and as of late, Pumas' and Adidas'size 11 offerings have been been fitting very narrow. I turned to these and I've been very happy with them. They have little arch support so I wouldn't suggest being too active in them (track running, tennis) but to wear out and about, they work well. And you have to love the retro styling (they were worn in the 1968 Summer Olympics held in Mexico City).
