The SIDI Spacer Arch Support Insole is a replacement boot insole designed to add arch support and cushioning inside compatible SIDI boots. It’s built for riders who want improved foot support aimed at reducing fatigue during long rides.
With an ergonomic, snug-fit shape, this insole is intended to help keep the foot stable and minimize pressure points over extended time in the saddle. It’s offered in multiple sizes and is made to fit a wide range of SIDI models listed on the page, making it a practical option for replacing worn insoles or upgrading for added support.
Comfort
Designed to provide cushioning along with dedicated arch support, the Spacer Arch Support Insole focuses on improving underfoot comfort for longer days in SIDI boots. The goal is better support through the arch to help reduce fatigue when rides stretch on and standing time adds up.
Aerodynamics
This insole is shaped to help maintain foot stability inside the boot while also working to reduce pressure points. For riders who feel hot spots or shifting inside their boots, the Spacer Arch Support Insole is intended to create a more supported, consistent feel throughout extended rides.
