*First appearing in 1977, the RoadRacer boots are revolutionary designs that use quilted panels on the front of the boots to provide flexibility and protection. It is a structure that holds the foot comfortably inside the boot, and even when worn for a long time, foot fatigue is significantly reduced compared to other boots. The calf-holding back strap is elastic, boasting a more sophisticated fit. *With anti-slip sole* It is made in units of 10mm, so those who end up with 5 units of foot size and those with high instep and wide feet should wear it an inch larger. (For example, the wearer of 265 mm 270 mm / 260 mm the wearer of a high foot and wide foot ball 270 mm) If you don't wear it with the zipper open, it can cause the zipper of the boot to fail.
