These bad boys are the go to for all my diving. They’re slightly negative, so for me they help keep my feet down in my drysuit. I find them really powerful, it’s easy to motor along with a frog kick, but also easy to make small movements in wrecks or to help position yourself perfectly. The big surface area makes back kick well too. Top that off with a super durable spring strap - no more broken buckles and your onto a winner!
