The K4 Flexy was the first model in the K4 Fins range. Designed with cross off conditions in mind the Flexy fin offers something no other fin does. The shape of the fin combined with the incredible K4 technology to provide the rider with unbelievable speed, grip and control when on a wave. The Flexy works better the harder it's pushed 'flexing' in the turns giving the rider a huge amount of grip and control.
K4fins boast a revolutionary material that set the fins apart from the rest. A plastic injection molded fin with long fibre glass strands the K4 material is re-writing the rule book in the fin market. Other brands are coming around to the flex idea but no one gets near what K4fins offer. A fantastic new concept that works in real world conditions.
