The Shimano ULTREAD GE rubber compound is optimized for enduro use, and its special profile ensures reliable pedaling and walking characteristics. The BOA® fit system features an L6 twist lock and plastic protection to prevent unintentional release during collisions with rocks and other trail obstacles. The TORBAL 2.0 torsion midsole offers flexibility on the outsides for excellent control on steep descents and corners. A stiff, carbon-reinforced midsole enhances efficient pedaling on connecting stages and climbs. The revised pedal channel runs from the heel to the toe area, providing excellent SPD stability when unclipped, while the elastic neoprene ankle protection offers additional defense against gravel and dirt.
