Editing Motorcycle boot (section)

====Transverse rigidity====
The transverse rigidity test determines how strongly the boot can resist your foot being crushed if a bike's weight fell on it. The boot is laid down with the widest part of the foot positioned between two plates. These plates squash together at a rate of 30mm per min. Apparatus records the force required to compress the sole at that rate. The machine is turned off when the plates stop squeezing the sole, when the force is clearly remaining constant or when the sole has been crushed by 20mm. This test is repeated three times. If it took less than 1kN of force to compress the sole to 20mm, the boot fails. If it took 1kN-1.4kN the boot takes a Level 1 pass and if it needed 1.5kN or more to compress the sole it achieves a Level 2 pass.
