Hey guys I didnt knew for the longest time. I have flat feet. Ans was always advised to go half a size larger than my actual foot size. Im a 10.5 (US), just recently I was advised to get 10.5 (Wide). I have tried it for tennis shoes, the difference has been marginal. The sole of the foot feels better but the toes still feel cramped. In dress shoes, example Thursday boots Chelsea's size 11 feels fine.
What has been your experience?
