So what do you suggest? Wetsuit booties? A few people on here (some cave divers even) suggest these;
NRS Paddle Wetshoes - Men's | REI Co-op
Warm and comfortable, the Paddle Wetshoes have zippered side entry that is easy to put on over bare feet or dry suit socks, making them an excellent choice for kayaking, paddle boarding and canoeing.www.rei.com
I am not a cave diver, so I have no dog in the race. But I can't understand the need for converses in any form for diving as the booties I just linked are inexpensive, have better thermal properties, and no laces?
Maybe converses are just a fashion statement?
Yes, wetsuit boots. I don't know anything about paddle shoes to have an opinion on them. The goal is nothing that can get caught. I had the vent of my Jet Fin snag a piece of rebar going through the locked gate at 130 feet in Vortex Spring. While waiting for my cave instructor to install a gap reel when I was first learning, my fin bumped the gate and I was snagged. My instructor's assistant had to remove my fin to get it unhooked.
