GRIP slip resistant sole is specially designed to prevent slippage. The sole is made of two materials with different elasticity properties that together with pattern design give the sole non-slip qualities. 

TPU-Thermoplastic polyurethane has properties including lightness, softness and elasticity. It is  resistant to oil and isolates coldness. 

TR-Thermoplastic rubber has  the properties and performance of rubber but is processed into soles by injection moulding like plastic. It is important to remember that TR-sole is not resistant to long-term use in oily conditions.

EVA-Ethylene vinyl acetate is a polymer that has qualities like high flexibility, excellent cold temperature isolation, stress-crack resistance and light weight.
