In the near future all high-end athletic equipment will be in some way customisable to fit an athletes body. Following the key concept behind Fi zi:k footwear, that of comfort and support leading to superior performance, Fi zi:k has partnered with SIDAS Technologies to produce the 3D flex custom insole. Professionally moulded in-store, the insole is moulded to your foot while in the cycling position. Weight is concentrated on the ball and arch area with the insole positioned to match the rise of the outsole. This precise custom fit and increased support will increase the efficiency of your feet and body driving power to the pedals thereby improving your performance and comfort.
