Designed in collaboration with the US military, its short wide blade maximizes thrust and maneuverability, while the oversized foot pocket ensures comfort with drysuit boots. A proven favorite among elite divers, this fin is engineered for performance in the toughest aquatic environments. ## Description Designed in collaboration with the US military and renowned for outstanding performance and reliability, the Apeks RK3 is a rugged thermoplastic rubber fin featuring an over-sized foot pocket to accommodate drysuit boots and a spring strap for easy donning and doffing. The RK3 is available in three sizes: Medium, Large and Super. We didn't give the RK3 fin a shoe size range as this can be very misleading. The 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. Therefore, 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.

Would these fit into a traditional carry on size bag?** A: They will easily fit into a duffle bag and should be able to fit into a hard carry on case, these fins are amazing easy to get on and off, very powerful I love them **Q: Please provide the size chart for this fins?** A: I don't believe there is a size chart, but with a 11-1/2" foot, along with the boot, I use a large and it fits perfect. The strap is a coil-like strap that stretches well, but does not become loose. Overall, these fins are great, I hope you find your answer and pick-up a pair. **Q: I wear size 9 or 9.5 and i have narrow feet. Would a large or a small fit better?** A: Thanks for the question. You are right in the middle of sizes. The Medium is 7-9 and the Large is 9-11. If your foot is narrow, you might be able to fit a Medium, but depending on the boot a Large might be better. Please let us know if we can help any further. Cody HouseofScuba **Q: My question may be very silly. The publication price is for the pair of fins?
