Aging comparison of two running shoes with different technology source Quote: Running shoes provide cushioning to the foot by the presence of a foam sole that dampens the impacts. However the mechanical properties can change substantially during usage, especially during the first kilometers. This modification is due to repeated cycles of loading and unloading of the material that the foam is made of and it can lead to variations in comfort and performances
