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.

Espectacular
Súper contento, mi mayor temor era la falta de potencia en un momento concreto, solventada la duda muy gratamente, muy maniobrable y cuando he necesitado darle caña me ha dado bastante más que mis anteriores aletas Mares.
En cuanto a la tienda todo perfecto, envio rápido, comunicación extraordinaria, en definitiva muy contento con todo.
