I wear size 12 in every brand of every shoe and have had several pairs of Puma and Adidas in size 12 They are tight and hurt toes. They are very small for a size 12 and will squeeze your feet and toes to the point of pain. I checked local stores and tried on a size 12 - no problem. Size 11 shoes appear to have a size 12 tag sewn on. WRONG SIZE, too small. I am extremely disappointed.
