SIDI revolutionized mountain bike shoe design with the Sole Replacement SystemŪ
(SRSŪ), allowing mountain bikers to replace the most wear-heavy part of the
shoethe sole. SIDIs global patent on the SRSŪ sole means SIDI is the exclusive
producer of MTB shoes with replaceable tread.
The SIDI SRSŪ
sole allows SIDI to maximize both traction and durability. Since the tread is
replaceable, SIDI can use an aggressive, softer durometer in the tread for
increased traction in slippery conditions.
