The relatively light weight of this Shoe is an integral element in determining its quality. In this regard, as in the beginning of the last century, manufacturers of a ugg carefully follow the "recipe", which is determined not only by the quality of the ingredients, but also their weight. Along with the use of traditional natural materials for Shoe uppers, linings and insoles today are manufactured with nano-technologies from artificial materials. The weight of such materials is significantly less than their natural predecessors.
However, if we analyze any pair of shoes, then, as a rule, the greatest weight has its sole. The ugg soles are made from special synthetic materials or rubber. They are very light.
