Because every body (and foot) is unique, Shimano's fully customizable SH-R310s could well be the ultimate road shoes. Thanks to Shimano's Thermo-Form technology we are able to heat mold the uppers and insoles of these shoes so that conform exactly to the contours of your feet. Your feet will then track perfectly allowing you to pedal more powerfully and reduce the possibility of injury to the knees and other joints. Of course, these top-notch shoes feature carbon midsoles for optimum power transfer, comfortable and durable synthetic-leather uppers, anti-slip heel cups, micro-adjust buckles, offset straps and walking tabs on the heels and toes.
