The Terra Powerstrap X4 from fi'zi:k was developed for all those who like to ride with racing handlebars, but also like to leave the asphalt track behind. The upper is made of abrasion-resistant polyurethane that is perforated for sufficient breathability. The sole is made of reinforced polyamide and has a rubberized surface with studs to keep you on your feet. The nylon footplate and the right stiffness ensure efficient pedaling. The Powerstrap velcro wraps around the entire foot for perfect support and comfort with just two strips.
