TPR, also known as TR, results of a combination of different raw materials. TPR means thermoplastic rubber, being that the type of TPR used in this brand offers a lighter density, 0,70 g/cm3, than the common TPR soles of 1,00 g/cm3. This means that the VP MICRO soles are 30% lighter than the conventional TPR soles. Flexible and with a good abrasion resistance – 150 mg – these soles can be produced in different opaque colours. The durability of the material is ensured along its use.
