Adjustable, powerful, and just the right length with an open heel and strap—these four features make Shack one of our most popular snorkel and dive fins.
Shack is a set of fins with the most popular foot type: open heel with strap. This design gives you great propulsion and natural maneuverability, making them super easy to use—even if it's your first time using fins. The strap gives your ankle extra flexibility, which a lot of people love.
You can easily adjust the fins on both sides with the unique one-click buckle system, so they fit your feet perfectly and are quick and easy to get on and off.
The big, flexible blade at the end gives you powerful kicks in the water for extra propulsion. Since the blade is so flexible, you'll use less energy and lower your risk of muscle fatigue and cramps.
The sole is made from non-slip material so you can stand your ground—even on wet surfaces.
You can wear your Shack fins barefoot or with socks, but the foot pocket is ergonomically shaped to give you the best experience barefoot. This unique shape also makes them comfortable for long snorkeling or diving sessions, plus the foot pocket is made from soft silicone.
When your Shack fins arrive, they come in a custom mesh bag that you can use again and again for storage and transport. The swim bag is made from black nylon mesh, so water drains out and your fins dry quickly.
