These are great fins. they have a much better foot pocket than jet fins. the large size is just slightly larger than a jet and much better fit in the pocket. if you are like most and need xlarge jets almost work than the regular lare size is for you. if you need bigger go for the super its nice and not a cave like the xxl jets. fins are modern and have nice straps and buckles the rubber is not quit as refined as the jet a lot stiffer and lighter! try em you will like them.
