Sidi ST Boots

Posted on: March 14th, 2013 by Road Rider MCA No Comments

Sidi ST street and sport riding boots offer serious support and protection for the track, the highway, and every twisty road in between. The ST is the only Sidi street boot that features the Sidi Cam-Lock buckle closure system, initially designed for use in Sidi offroad boots. Similar to the buckle system on a ski boot, Sidi Cam-Locks offer the best in security and customizable bracing, but they are still fast, durable, and incredibly easy to use.

The Cam-Locks pull together the shin plastic and ankle brace system securely around your calf, and the hinged ankle brace allows easy forward mobility while contributing heavy-duty exterior ankle protection and stability. Effective venting for the track is provided by closeable vents on the outside of the foot. The STs also feature Sidi’s top-tier bolt-on heel cups for maximum heel protection.

For a technical boot with race-level protection and a reliable, no-nonsense entry system, look no further than the Sidi ST.

Note: Riders with larger calves or wider feet who have tried other Sidi road race boots like the Vertigo may find the Sidi STs more comfortable.
