POwerfins CMAS bifins - hard

Very hard fins for sprint-finswimmers. Also recommended for strong UW-rugby players. POwerfins CMAS bifins are made to be the fastest fins when monofins and fins with fiber-blades is not allowed. 100% polymer (TPE rubber) and approved by CMAS for finswimming bifins championships. The hard model is very stiff and made for sprinting 50 (and perhaps 100 meters if you are a top level athlete). For longer distances or aerobic training always choose softer fins! PLEASE NOTE! Foot pocket sizing: The instep is narrow and the fit is tight for optimum stability and power transmission. Therefore, it is recommended to use soap when putting on the fin. Dip your feet and fins into the water, soap your feet and the inside of the foot pockets before stepping into the fins. Fit and comfort are absolutely best in combination with neoprene toe caps. To make it easier during training, you can choose the next larger size, but don't oversize for racing! Remember; do not forget the soap! Material: 100 % polymer (TPE) Rubber hardness: 65 Shore Good resistance against sunlight and chlorine Made in Europe. International top level finswimmers all over the world compete and train with POwerfins.
