Flexural cracking resistance of sole

During the whole service life of a shoe, the sole must be constantly bent without cracking or breaking. This paper introduces the test method and equipment for evaluating the flex crack resistance of soles.

Due to the strain caused by foot bending, the sole may wear, crack or break. It will also crack or break due to the cutting and piercing of sharp edges, and will gradually become cracks when it continues to buckle. Extreme temperature (especially below zero) and pollution (such as engine oil) may also accelerate the cracking of soles.
