A high-end competition road shoe from Shimano, the R171 uses Shimano's new Dynalast technology to maximise your pedaling efficiency and the offset strap system helps relieve tension at the highest part of your foot for greater rider comfort.
A shoe designed with competition in mind. Features such as Shimano's Dynalast, offset straps, wider cleat adjustment and the dual density cup insole all aid and help you to maximise your pedaling efficiency and provide total rider comfort at all times. The innovative Surround upper pattern provides perfect balance of holding power and absolute all-day comfort by wrapping the foot in a way that is securer and more comfortable than any previous designs.
Dual Density Cup Insole
The cup of this insole serves to optimise the heel angle and ensure stability while pedaling. This insole is equipped with a hard, high density, and highly durable EVA heel cup.
Unlike conventional closures, Shimano's anatomically precise offset straps relieve tension at the highest point of the foot, where pressure tends to be greatest.
Dynalast Shoe Technology - creating pedaling efficiency
The toe-spring section of a cycling shoe plays a key role in supporting efficient pedaling. Too high, and it causes increased tension in the plantar, calf, and hamstring muscles. Too low, and you get a bowlegged, inefficient pedaling form.
