The Shimano Ultrad GE rubber compound, optimized for enduro use, and its special profile ensure reliable pedaling and walking characteristics. The Boa fit system with L6 twist closure and plastic protection prevents unintentional loosening during collisions with rocks and other trail obstacles. The Torbal 2.0 torsion midsole provides flexibility on the sides for excellent control during steep descents and turns. A stiff, carbon-reinforced midsole ensures efficient pedaling during transition stages and climbs. The redesigned pedal channel that runs from heel to toe guarantees excellent SPD stability when unclipped, while the elastic neoprene ankle protection offers additional defense against gravel and dirt.
