The Sport RBX is perfect if you're looking for an SPD-compatible cycling shoe you can walk in, which is noticeably lighter and stiffer soled than most MTB/leisure cycling shoes.
This shoe is good for any road riding from general tootling around and commuting to all-day sportive and touring.
RBX is Specialized code for Roubaix - their award winning road bike range, famed for combining rider comfort with Paris-Roubaix-winning performance.
Body Geometry shoes are the fruit of a collaboration between Specialized bikes and Dr Andy Pruitt: sports scientist, author, one-time US national team coach and a world expert in cycling-induced tendonitis.
The contoured Body Geometry footbed supports two key areas of the foot: the metatarsal and the longitudinal arch.
The raised metatarsal button section of the BG shoe's footbed spreads the metatarsal bones. This helps prevent pressure on the nerves and blood vessels, thus helping to reduce 'hot spots', swelling, and general foot discomfort.
The footbed's raised longitudinal arch support provides a stable platform to minimize arch flex and improve power transfer and efficiency.
The varus wedge slightly angles the forefoot to match its natural canted position, bringing the foot into full contact with the pedal and eliminating rotational movement of the knee, shin, and foot. Compared with riding in standard shoes (cycling or otherwise) Body Geometry shoes help keep your leg better aligned and encourage a smoother pedalling stroke, and therefore help prevent foot pain and knee strain.
