OEM Fins

The short blade is specifically engineered to increase resistance while forcing a faster, more compact kick cycle. This helps you develop better ankle flexibility and proper kicking technique compared to longer, recreational fins.

Yes, they are versatile enough for both. The silicone construction is durable enough for chlorinated pool environments, while the compact profile provides the necessary propulsion and efficiency required for breath-hold and freediving sessions.

Since these are full-foot fins, you want a snug, secure fit without any pinching or pressure points. If you are between sizes or plan to wear them with neoprene socks for colder water, we recommend sizing up to ensure comfort.

The silicone used is flexible and designed to conform to the foot, which generally reduces the risk of chafing. However, like any new swim gear, it is a good idea to break them in during shorter sessions to ensure the fit works with your specific foot shape.

You should choose these if your primary goal is technique development or travel convenience. Long blades are better for leisurely cruising, whereas these short blades are a training tool designed to build leg strength and improve your stroke efficiency.
