Sidi MTB SRS Metatarsus Insert - Yellow 41/44. The Sidi MTB SRS Metatarsus Insert is a specialized insole component designed for Sidi’s mountain bike shoes equipped with the SRS (Sole Replacement System). It is engineered to provide targeted support and protection to the metatarsal region of the foot—an area prone to pressure and fatigue during intense cycling.

The insert is built for durability and visibility

Enhances foot stability and comfort by redistributing pressure across the metatarsal area helping to reduce fatigue and improve power transfer during rides

Specifically designed for integration with Sidi MTB shoes that utilize the SRS sole system allowing for easy replacement and customization
