These shoes run very small! I'm a 8 1/2 normally in Nike sneakers but the 8 1/2 was very small on me so i ordered a size 9 which would have been comfortable except for the fact the shoe it self is very tight. I wear the sneakers for about 20 minutes and it felt like my feet were losing circulation. Even with a size 9 my feet had no room to breath. I'm 5'7 and 130 pounds. I would not advise anyone to make this purchase."
