I wear a 14 wide men's trousers and ordered a size 15. I am very happy with the fit of the shoe and how well it glides as I move my feet during Tai Chi sessions. I had trouble finding these shoes in my giant size and fully expected to return them. Not only will I be keeping them, but maybe ordering a few more pairs for storage (just in case) and ordering another pair for indoor shoes. I would like to thank the seller for the sensitive attitude to heavy-legged people.
