The Gaerne SG-12 is Gaerne's top-tier motocross and off-road boot, built in Italy from cowhide leather with plastic protectors. Its signature feature is the Dual Stage Pivot System, a two-part ankle joint that limits sideways flex while letting the foot move naturally front to back. A perforated shaft and a screw-adjustable shin plate round it out. Riders rate it among the most protective boots in its class and often compare it to the Alpinestars Tech 10 and Sidi Crossfire; the trade-offs are weight and a stiff break-in.

Owners and testers consistently praise the SG-12 for its protection, build quality and fit once broken in. Most criticism centers on weight and a stiff first few rides.
The Gaerne SG-12 is a black motorcycle boot made from cowhide leather with plastic protectors. The lining is microfiber, the buckles are aluminum, and the calf has GRIP-GUARD synthetic heat-resistant protection. The shaft is perforated for ventilation and is about 37 cm tall.
The boot uses the patented Dual Stage Pivot System, a dual joint design that stabilizes the ankle while keeping a flexible range of motion. Three screws on the shin front plate adjust the calf width, and the adjustment also leaves room for a knee orthosis. The footbed is anatomically shaped, and the insole is replaceable and washable.
