The shoe is designed with a three-point fastening system. An important role on it is played by a fixed buckle, ensuring a precise fit and secure fastening, and two Velcro straps. The middle one of the strips adapts to the shape of your foot, and the second ensures the distribution of pressure so that there are no bruises in the area of ​​the toes. The buckle and strap can be replaced.

The R250 road sole is equipped with new injected fiberglass and designed with arch support along the entire length of the foot. The two-layer composite insole cushions the impact on the road, and the nylon mesh openings help with ventilation.
