Tritan Silicone Fin

Because these fins feature a stiffer durometer, they are designed specifically for resistance training. While they can be used by anyone, they are best suited for swimmers looking to actively build leg strength rather than those just learning to kick.

The adjustable strap allows you to customize the tension around your heel, which is helpful if you are between sizes or prefer a tighter lockdown. It also makes the fins more versatile, as they can accommodate different foot shapes more easily than a fixed, closed-heel design.

These fins are engineered specifically for pool use. The stiff silicone construction is optimized for the controlled environment of a lap pool, and they may feel too rigid or heavy for long-distance open water swimming.

The silicone is soft and flexible, which generally minimizes friction. However, because these are stiff training fins, we recommend ensuring the strap is adjusted correctly to prevent unnecessary movement against your skin.

At 16 ounces, these fins provide a noticeable amount of weight, which is intentional for strength training. While they will provide lift while you are actively kicking, you will feel the weight if you stop moving your legs, which serves as a good reminder to maintain your kick rhythm.
