Oceanic Drysuit Shoe Boot Neoprene for Repair Replacement
NOTE... These fit one size smaller than they say. A 10 US fits like a 9US so order one size up.
Do you have a drysuit with attached boots that don't fit you ? Are you a DIY kind of person ? These are boots that you need to change on your drysuit. 3mm neoprene for thickness at the top and roughly 12 inches high.
