I bought a size 10 first & they squeezed my feet so much so I sent them back after trying them on & ordered an 11 thinking they would fit better I was not sure about them because I usually wear a 10.5 but they didn't have that size & because they were not wide enough in a 10 I had to order an 11 so anyway I wasn't real sure of the 11's but they grew on me & I figured I could put a shoe insert in them then they'll be perfect I am so glad I kept them because they are sooo comfortable now I want a black pair I really need black. I kind of wonder if I would've stretched out the 10's if they would've worked I might try that next time.
