Studies were designed, experiments were conducted, materials tested. The results all suggested that visco-elastic polymers were the optimum materials for underfoot cushioning. These synthetic materials, which are both dense and elastic, proved remarkably able to absorb the shock of heel strike. Taking up less space in the shoe than conventional foam materials, visco-elastic polymers are the most efficient form of under-foot cushioning available today. In fact you would need up to 15 drug store insoles to equal the cushioning effect of one visco-elastic insole.
In tests that actually measured the amount .
Due to fashion trends and cost cutting by manufacturers modern footwear rarely has sufficient cushioning. Most sports shoes which should offer better protection are rarely Read More.....
