So I currently have 2 pairs of these pairs, one is a size 13 black pair and a size 13 white/red pair. I would say they are slightly larger than other brands but they are slightly larger. By the way, I usually take a size 12 or 12 1/2. These are amazing shoes for comfort and good sole grip. Casual running/casual exercise is fine, but not recommended for anyone who wants to run and/or play seriously. Sports. I've since bought two more pairs and they're on the way! The black/red size 13 comes on Saturday 25.06. and another white/red size 13 BUT it's weird and I don't have a delivery date yet but that's really my only complaint about these shoes. I would/will recommend these shoes to you!
