All our soles: Mountain, Sport, food and Clasic, exceed the required non-slip coefficient of 0.15 and are slip resistant between 55% minimum and 78% maximum. (according to method ENV 13.287:2000).
Made up of two types of sole and two different designs, but with the same physical-dynamic characteristics. The sole tread has an influence on the non-slip coefficient and the bending resistance.
The general technical characteristics are the following:
Wear and tear resistance, bend resistant, hydrolysis and hydrocarbon resistance much higher than required by the standards. Low thickness and stable model to obtain maximum comfort and good energy absorption on the heel.
Using special additives, the electrical resistance values and cold and heat insulation have improved. Similarly, chemical product resistance as also improved.
