The Apeks RK3 is a rugged thermoplastic rubber open heel fin with a short, wide vented blade and spring straps as standard. Apeks bases it on one of the first vented rubber fins sold in North America, and the design has been standard issue for military, special ops, coast guard and public safety divers for decades. This page offers the RK3 in black, pink and yellow; choose your color and size from the options on this page.

Key Features

• Short, wide blade for strong forward thrust with great maneuverability
• Vented blade reduces resistance on the upstroke and enhances thrust on the downstroke; the vents also eliminate the vortexes that form behind the blade
• Oversized foot pocket built to take drysuit boots
• Spring straps for easy donning and doffing, even with cold hands or thick gloves
• Custom buckle holds the springs in position, and a simple push pin design lets you replace them if needed
• Two grommet holes fit most carabiners for easy carrying to the dive site

Sizing

• Apeks does not give the RK3 a shoe size range, because wetsuit boots and rigid drysuit boots of the same shoe size fill the foot pocket differently; bring your boots and we can help
