NOENE Shock-absorbing insoles Why Noene? Nočne is a high-tech vibro-absorbent elastomer made from a unique composition of crystalline rubber micro cells. Formulated to a patented design it gives properties vastly different to normal rubber. So effective is the composition that for most runners just 2mm thick will damp upto 99% of shock forces imparted from ground contact. Ultra Lightweight (lightest available). Low Profile. No need to buy a bigger shoe. Can be used with orthoses, spikes and racing shoes - in fact any specialist footwear. Does not diminish feel of ground contact or orthotic support. Excellent cushioning (Elasticity). Unparalleled energy dispersion (Shock attenuation or damping). Amazing durability - far outlasts any comparable product. Remains stable even when wet. Absorbent lining (Absorbs twice it's weight). Competitive prices (All these advantages & no more to pay!) The impact force with which a foot strikes the ground will rebound off the surface and vibrate up through the body as an energy shockwave, affecting muscles, tendons and joints. Damage caused by these rebound shockwaves can build up over time, to such an extent that the problems like tendonitis and back pain will result. Originally man moved barefoot over naturally elastic or cushioned terrains like grasslands and forest floors. Hard rocky areas were then avoided, unlike today when we have to endure rigid, non-elastic surfaces like concrete and asphalt that do not absorb these shockwaves, even though we now wear shoes.
