SIDI · Boot Parts
The SIDI Vortice Ankle Support is a replacement ankle support set made to fit SIDI ST and ST Air boots. Sold as a pair, it is designed to add ankle stability while still allowing flexibility, helping riders maintain control during demanding rides.
Offered in Black/Red and two size ranges, 39-42 and 43-48, this set makes it straightforward to match the correct fitment to the boot size range and refresh worn or damaged ankle supports without changing the rest of the boot.
Aerodynamics
Designed to improve stability while maintaining flexibility, the Vortice Ankle Support targets ankle support and control where the boot needs it most. Because it is sold as a pair, both sides can be replaced together for consistent feel and full ankle coverage on the boot.
