I usually get a half size and I cut it in half. Even then, it was a little longer than a perfect fit. Good water shoes. I use them on the beach and even swim in them. I only recommend them as water sports/beach shoes.
Pros
I haven't used them for canoeing yet. The fit is great for wide feet. Stretchy and comfortable
Cons
Began to fall apart in a few places where the rubber stuck to the shoe on first use.
