I wear a 9.5 wide redwing boot. But decided to go with a 10 regular. Definitely go up a half of a size from a boot and a down a half of a regular shoe size. Extra width was not necessary at all. Love these shoes. Lightweight but not mesh. love the leather slide heel. And obviously the boa system is the best part. Not having to adjust my shoes after each game is great. Only complaint which is not enough to take a star away, would be the boa being on the back instead of tongue or side. Only because you can't be lazy and slide the shoe off by just stepping on the back with the opposite foot without relocking it. But overall great shoes very comfortable. Highly recommend
