The Sidi E1 SRS Enduro Sole is an ideal replacement for riders using Crossfire 2 SRS boots who demand superior traction and durability on challenging terrains. Designed with heavy-duty lugs and an aggressive tread pattern, this sole provides enhanced grip without adding noticeable bulk. Built from tough materials, the E1 SRS Enduro Sole retains the rugged resilience of the original, while maintaining precise foot control. Installation is straightforward, using the same screws as other SRS soles.
