So why are Jetfins ok in a cave?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.
