You'll really love/like these shoes.....they come out of the box comfy! I walk 30 blocks a day/ 5 days per week and on the first day of wearing them my feet were like "where ya been all my life?"  I've tried all the major brands of athletic shoes and nothing fits like Adidas....the others were either too wide or just a bit too small making my toes (big toe) crammed up at the top and not very comfortable.
I wear a true size 11, however I buy the 11.5 for that touch of extra socks room.
