The RK3 is available in three sizes: Small, Medium, Large and Super.\u003c\/p\u003e\n\u003cp\u003eWe didn't give the RK3 fin a shoe size range as this can be very misleading.\u003c\/p\u003e\n\u003cp\u003eThe environment that an RK3 is used in will tend to dictate the size of fin that you need, for example do you dive in a warm environment wearing wetsuit boots, or are you walking across pebbled beaches and wearing a drysuit and rigid dry boots? Both forms of footwear may be a size 9, but will take up different amounts of space in the fin foot pocket.\u003c\/p\u003e\n\u003cp\u003eTherefore, we recommend that you visit your local dive store and try the fins on with your own footwear, just to ensure that you're getting the right fit for your style of diving.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures: \u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBased on one of the first vented rubber fins sold in North America

divers for decades.\u003c\/li\u003e\n\u003cli\u003eShort wide blade provides maximum forward thrust while maintaining great maneuverability.\u003c\/li\u003e\n\u003cli\u003eVented blade design reduces resistance on the upstroke and enhances thrust on the downstroke.\u003c\/li\u003e\n\u003cli\u003eThe vents also eliminate vortexes that can occur along the back of the blade much in the same way split fins eliminate the vortex.\u003c\/li\u003e\n\u003cli\u003eThe blade material designed to hold up in the toughest environments, temperatures and abuse.\u003c\/li\u003e\n\u003cli\u003eTwo large grommet
