Apeks RK4 Fins – Precision, Power & Comfort

The new Apeks RK4 Fins deliver optimum performance. They excel at frog-kicking and back-finning. These fins are not too heavy or excessively rigid. Consequently, you conserve energy with these compact, wide-blade fins. 

They provide outstanding maneuverability in confined spaces. Equally, they perform well in overhead environments. Enjoy easy finning in open spaces, whether upstroke or downstroke.

Enhanced Blade Design for Maximum Control

Apeks increased the blade's side edge for greater control. However, they retained some flexibility at the fin tip. This prevents the fin from feeling too rigid, ensuring a balanced blend of power and comfort.

Adjustable Fit & Hassle-Free Donning

The Apeks RK4 Fins feature an adjustable fin spring strap.  This strap can be adjusted forward or back 2cm. Consequently, this ensures an optimal fit.

Furthermore, a large, durable pull at the back simplifies donning and doffing.  This is particularly helpful with a drysuit.  Finally, divers concerned about entanglement can remove the pull-handle, while the rubber guard on the spring strap remains intact.

Balanced Weight & Versatile Use

The Apeks RK4 fin's weight falls between the RK3 and RK3 HD. It is neither super heavy nor too rigid. Therefore, it's comfortable in a drysuit or wetsuit. In short, the RK4 is a great all-around fin.
