I love vibrams for diving. Having your toes separated eliminates foot cramping in open heel fins, as well as helps with a more effective frog kick. I wish vibram would make a dedicated neoprene bootie for diving. I chose the Spyridon MR Elite due to its appearance of having fewer velcro straps and laces. You don't want anything irritating your foot inside a fin pocket. Unfortunately they do have a hidden set of laces. I cut the laces out and these shoes have lasted me 500+ dives. I was especially impressed with the grip the soles have on slippery, wet surfaces when walking over algae covered rocks for shore diving.
