I wear a size 12 of every brand of shoe and have had several pairs of Puma and Adidas in size 12. They are tight and sore 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.
