Sidi RSUCRSRS-40 SRS Sole Kit for Cross Shoes

Sidi RSUCRSRS-40 SRS Sole Kit is a replacement outsole for SIDI Crossfire SRS boots in size 40/42, listed under the RSUCRSRS – SRS SOLE designation in Sidi’s spare-parts catalog. This kit is part of the Cross/SRS family of soles designed for models that use the SRS sole interface and is specifically intended for Cross models that wear the SRS sole. The catalog also groups RSUCRSRS by size bands beyond 40/42, including 43/44, 45/46, and 47/48, reflecting the range available to fit different riders. By replacing the worn outsole rather than the entire boot, the RSUCRSRS-40 kit helps maintain the original boot’s fit and compatibility with Sidi’s sole geometry while restoring traction on off-road conditions. This genuine SIDI replacement part is associated with the Cross/SRS footwear ecosystem, particularly the Crossfire SRS line, and is intended for compatible Crossfire boots. Before ordering, confirm that your specific boot model and size align with the RSUCRSRS-40 variant to ensure a proper fit.
