ICEBUG Sisu OLX is built for high speed in tough terrain. The traditional lacing system has been replaced by BOA® Fit System, guaranteeing a perfect fit and speeding up the process of taking the shoe on and off.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. OLX is an Icebug technology with fixed studs, delivering the best possible traction on all surfaces nature has to offer.
