What does it test:

It tests the resistance of soles on flexing movements.

The anatomy of walking requires flexing of the shoe in the metatarsal area. Consistent sole flexing can cause cracks, which lead to reduction of functional characteristics of sole and whole footwear (comfort, water resistanceâ??). The possibilities of cracking are even higher in cold conditions. By pre-testing a producer can identify potential problems and anticipate cracking of the sole, which causes customersâ?? dissatisfaction and increases his purchase costs.
