Sidi Crossfire 3 SRS Boots

Sidi Crossfire 3 SRS Boots
SIDI Hyperextension Block is an entirely new mechanism.
This Block provides freer movement to the ankle in actions such as changing gears while reducing lateral flexion of the ankle, called hyperextension.
Therefore, we have more comfortable but also safer boots.

Also, the heel area has redesigned. On the instep and toe of the boots, we now find more polyurethane.

Which means excellent resistance to the boot and also, which provides improved grip on the shift and brake levers. Extensive work has done on the shank of the boot to incorporate SIDI’s patented calf extension system.
The boots cover the legs by two rigid elements, one outside with polyurethane protections and another supplementary protection inside.
This system allows varying (using screws) the anchoring of the protections, which are attached to the external rigid element.
The means that by varying the anchors, we gain in calf diameter, being a versatile boot to our morphology.
The Crossfire 3 SRS improved this system, as it now offers more adjustment possibilities, both in the front and rear protections of the rod.

The Crossfire 3 SRS follows the path of its predecessors.
The lining from the ankle area to the middle of the leg in ventilated mesh with Teflon treatment, which prevents the absorption of water and sweat.
The upper part of the shaft lined with a soft mesh and has special padding on the shin. And on the toe, we find a Cambrelle lining that is highly resistant to abrasion and provides rapid moisture absorption, ensuring a high level of quick drying.

One of the great features of the Crossfire SRS is the sole replaceable system, which gives the model its name (Sole Replacement System).
