Uses newly developed rubber for finsAdopted rubber for fins that not only improves elasticity but also improves durability. Naturally, the material will deteriorate when diving in seawater or in the sun. However, because the fins are important for obtaining propulsion, we pursued long-lasting and safe use. Strong suppleness like a whipThe fin-specific rubber with excellent repulsion is used to efficiently generate propulsion with a whip-like snap. Even with less leg strength, you can swim with the same driving force as a general rubber fin. Discerning foot pocket shapeTexture is applied to the inside of the foot pocket to reduce friction. The bottom of the foot pocket has a protrusion to reduce the contact area with the boot and improve the ease of putting on and taking off the boot. In addition, the bottom of the foot pocket opening is smoothed to make it easier to insert your feet.
