When placing my order I was unsure whether the 7 would fit me, I wear a 6 1/2 in regular shoes and 7 in all of my athletic shoes, and after reading the other peoples suggestions on going up 1/2 size I decided against it and I was right on the money, my rykas fit me perfectly, I tested them out at the park for a run last night and they were very comfortable compared to my nikes.
