Rubber / Silicone Shock Absorption

Rubber shock absorption is the most "old" way to absorb shock. The reason why it is old is that since the electric treadmill has been used, it is the first material used in the shock absorber structure of the treadmill. Because rubber has the highest elasticity, weather resistance and cost performance before it has more new materials, it is the most widely used. So after the silicone was used, it was widely used.
