Sisu RB9X™ is a built for high speed in all kinds of terrain and weather. The traditional lacing system has been replaced by BOA® Fit System, guaranteeing a perfect fit and speeding up the process of taking the shoe on and off. The BOA® Fit System also improves the midfoot hold and support which in turn results in an improved running economy. The upper material is a bluesign® high abrasion recycled PET polyester with a protective TPU mudguard – very smooth and with a thin and direct feeling. Sisu has a low drop (4 mm), low sole profile and excellent ground control, ideal for technical trails and off-trail running. The outsole is crowned with the jewel among sticky rubbers: RB9X™. This innovative rubber compound provides incredible traction on both wet and dry surfaces, without compromising durability!
