Redesigned for lighter weight and more efficient power transfer. Ergonomically designed & scientifically tested Body Geometry footbeds were co-developed with Andy Pruitt, Director of the Boulder Center for Sports Medicine, to customize fit and measurably improve performance. Body Geometry footbeds provide longitudinal arch & metatarsal support for a custom fit By standing on the Specialized Arch-O-Meter, a rider can determine the optimum level of foot contour: + Red = minimal contours for riders that prefer minimal support ++ Blue = moderate (slightly higher longitudinal arch & metatarsal button) = for people with flat to standard arch +++ Green = significant support = for people with standard or high arches Body Geometry shim and wedges sold separately
