The SIDI Calf Section is built to reinforce the upper portion of the boot, helping maintain structure, coverage, and a secure fit during aggressive riding. Designed for durability and long-term performance, this replacement panel provides an easy way to refresh worn components while preserving overall stability. Offered in multiple color options, it allows riders to restore both function and appearance without replacing the entire boot. Installation is straightforward, making it ideal for routine maintenance and long-term care.
