The Kaptein Custom Footbed / Soles service is a professional in-store heat-moulding session where Kaptein's fitting specialists shape a Specialized Body Geometry Custom Footbed precisely to your individual foot profile. The process takes 20–30 minutes and corrects biomechanical imbalances including arch support, forefoot varus, and supination — issues that contribute to knee pain, hot spots, and inefficient pedalling. Recommended as a companion service to a bike fit or purchased alongside a Custom Footbed product. At €129, it's one of the most cost-effective interventions for chronic foot or knee discomfort on the bike.
