The Fourth Element Tech Fins are a modern take on the classic vented fin design. They are made from a unique density gradient of natural rubber, offering a comfortable foot pocket and optimized stiffness for superior finning performance. The vented design allows water to flow along the blade, reducing drag and fatigue.
While the Tech Fins were developed with technical divers in mind, they are suitable for all levels of divers looking for a high-performance rubber fin.
The Fourth Element Tech Fins are part of the OceanPositive range and are made from recycled, natural, and recyclable materials. They come in zero-plastic packaging, reducing plastic waste and environmental impact. At the end of their life, all components of the fins are recyclable.
The spring straps on the Tech Fins feature comfortable heel pads and ensure a secure fit. They can be easily removed and replaced with everyday tools if necessary.
The hanging/carrying strap allows you to attach the fins to a BCD or harness for easy transport, freeing up your hands for other gear.

Great fins. Absolutely love them. Small but plenty powerful. The only downside is the grey color mares easily if you're one to get into tight spaces on wrecks. Gives them a bit of a well-used look.

Got these fins last summer. I've been using Apeks RK3s and after using these, they've become my primary. Reversing and maneuvering are a bit easier in these fins, not that it was difficult in the Apeks. The sizing is different than the Apeks. I use a super in RK3 and with the 4th Element I'm a 2XL.

With classic designs that are kinder to the planet and optimized for performance and efficiency, whether recreation or technical diving, there's a pair of Fourth Element fins however you explore. Part of Fourth Elements OceanPositive range, they've used recycled, natural and recyclable materials in the manufacturing of their fins and each pair comes in zero plastic packaging, eliminating plastic waste and reducing the impact on the environment. A classic vented fin, redesigned to maximize performance. Utilizing natural rubber in a unique density gradient, this fin delivers a comfortable foot pocket combined with optimized stiffness for finning performance. The vented design allows water to flow along the blade reducing drag and fatigue, whilst the stiffening rails and ribs ensure that the blade of the fin is driven through the water to maximize the return on effort.
The Tech Fins was developed with technical divers in mind with a slightly negative buoyancy characteristic but is suitable for all levels of diver looking for a high-performance rubber fin. The wider blade gives maneuverability without compromising the power which is there when needed, while the shorter length improves agility and makes stowing the fins for transport more convenient. Spring straps with comfortable heel pads keep the feet securely held in place and these spring straps can be removed and changed easily with everyday tools if required. The Tech Fins is supplied with a hanging/carrying strap which may be used to attach them to a BCD or harness for carrying, leaving both hands free for climbing ladders or carrying other gear. The natural rubber material of this fin is extremely durable, and all components are recyclable at end of life. Fin is available in multiple sizes and colors.
