The sole dimensions in the toe and heel boot binding interface areas shall be symmetrical about the median plane within an admissible deviation of 1 mm. There shall be no protrusion of the sole beyond the shell for the whole perimeter of the whole boot sole interface areas. The design of the toe and heel boot binding interface areas shall not negatively influence the function of the binding. Side walls at boot toe The side walls of the sole at the boot toe up to a distance of at least 25 mm from the toe end shall be perpendicular to the bearing surface within an admissible inward-outward deviation as shown in Figure 1, section C-C. If the side walls of the sole are built in two parts, it shall be ensured that no part of the lower area of the sole protrudes beyond the upper profile. Cut outs with an outside diameter of not more than 5,5 mm with a centre in 14 mm土1 mm from the tip and 6,5 mm士1,5 mm surface from the top surface are allowed (see Figure 2). Different material than the shell material around the hole is allowed, if the surface is in line with the flush material.The lateral side walls of the sole at the boot heel up to a distance of at least 70 mm from the heel end shall be perpendicular to the bearing surface or tapered inwards-outwards between 0° and 10° up to a height of 14 mm.If lateral grooves of more than 2 mm depth are present at the heel (see Figure 3), supports at least complying with Figure 4 shall remain. Other configurations of grooves are allowed if they are within the given dimensions in Figure 3 Figure4 and Figure 5.The coefficient of dynamic friction is determined by the ratio of the force F1, necessary to move a lowfriction element over the two interface areas of the boot, to the test load F2, which is applied to the lowfriction element.BS ISO 9523 pdf download.
