Alright, I have a 10.5 4E foot so I go up to a size 11 and these AI's are extremely comfy. I am also 6'2, 253 pounds( Not fat in the gut but wide) and these shoes held up nicely for me in my local YMCA league. I usually play in my Jordan XlV's White and Red or my ZK1 Black and White but I decided to try out them AI's since they were on sale for 69.99 and I heard good things about them. Just to warn though, certain peoples feet may not be comfortable in these shoes performance wise. IMO they are the third best performing Answers. Answer 1 and Answer 3 were the best performing AI's to me.
