Giro Chamber III Shoe - Black/Black ENVEMARCH The optimized tooth profile andThe all new Chamber III brings a new level of performance to our SPD compatible mountain 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.
