The wide fits like a regular shoe.  I really wish they had a double wide option. The band across the top of the shoe is completely pointless and unattractive. Because of the band, I cannot stretch the shoe out any wider which makes this my go-to shoe for short runs only. My feet swell up on longer runs and these would not work. If you aren't used to minimal shoes, these take a while to get used to especially if you're running in them. I've seen people injure themselves in minimal shoes by not giving themselves enough time to adapt. Build up your miles slowly in these. The sole doesn't grip enough on the trails, especially in slick or muddy conditions. It's more of a road shoe sole.
