Giro Chamber Trail Shoe World Cup DH power transfer. Trail-ready everything else. The Giro Chamber Trail is built on the same tri-molded DH platform that's won at the World Cup level - delivering the power transfer and pedal precision of the original Chamber in a shoe reimagined for the demands of modern trail and enduro riding. A new microfiber upper with integrated mesh ventilation keeps things lighter and cooler than the DH version, a closed-knit ankle cuff blocks out debris on technical terrain, and a single BOA(R) Li2 dial with injection-molded lace guides provides precise, micro-adjustable fit with the turn of a dial. Giro's proprietary Sensor rubber balances grip and durability underfoot, and a +10mm optimized cleat setback improves comfort and efficiency across long days on progressive terrain.
