2025 Giro Chamber III Shoe
GiroThe podium-proven durable and secure trail shoe reimagined in a lighter and sleeker shape
The all-new Chamber™ III brings a new level of performance to our SPD-compatiblemountain bike trail shoe. Lighter and slimmer than the previous iterations of the EWS and World Cup-winning Chamber, this shoe is ready to send it downhill but delivers plenty of power transfer when it comes time to pedal. A supple microfiber upper conforms to your foot for a locked-in feel and a new low-bulk tongue help make the Chamber III our lightest version yet. Simple, secure retention from Velcro hook-and-loop lock down strap and laces adapts to varying foot volumes, while a Giro-specific Sensor rubber outsole pairs grip and durability. At the heart of the shoe, the clipless-compatible DH plate with +10mm optimized cleat setback strikes the perfect balance of stiffness and walkability. Deliver secure, durable power to your pedals with Chamber III.

Features
Microfiber Upper
Lightweight yet durable, the Microfiber Upper is water-resistant yet breathable, and supremely comfortable. Paired with a comfortable, non-restricting, fully-wrapping bulk free tongue.
Velcro® Powerstrap
Velcro® hook-and-loop Powerstrap works in conjunction with laced closure for superior heel lock-down, added security and support.
Rockprint
Rockprint reinforcement along the toe and heel offers added protection and durability in high-wear areas.
Sensor™ Rubber
Giro's proprietary rubber formula balances grip and durability without sacrificing light weight. The rubber outsole is co-molded with the carbon composite plate to deliver a permanent, glue-less bond.
Custom DH Shank
The Chamber III custom DH shank features a cleat position that is 10mm further rearward vs. our other MTB shoes. This ensures an even more stable platform for descending, while still enabling efficient pedaling.
