notes: label: Description
content: These cycling shoes were used by American track cycling World Champion Sarah Hammer (b. 1983) and were worn between 2010 and 2011. Manufactured by Specialized Bicycle Components, the shoes were first released in the winter of 2009 as a part of their top tier S-Works line of bicycles and equipment.
label: Description
content: Hammer’s S-Works shoes incorporate several features that are specific to cycling footwear. The soles are made using carbon fiber, which is an extremely light but rigid material. A rigid material is preferred, since flexing under load reduces the rider’s power output as they perform their circular pedaling motion originating at the leg, through the shoe, pedal, and crankarm. A Shimano brand cycling cleat bolted to the sole of the shoe locks into a road cycling pedal, which allows the rider apply more power throughout the pedal stroke. The shoe’s uppers are constructed of synthetic leather, which is more resistant to stretching than real leather. The two dials on the uppers of the shoes are a proprietary system made by Boa Technology that independently tightens and loosens a steel lace and are easier for the wearer to adjust the fit of the shoe while riding than Velcro or laces.
