how its works

The purpose of any shock absorbing insole is to cushion the body column from the impact of heel strike. The energy force caused by heel strike is absorbed by the insole material. As the heel lifts off, the insole material rebounds, releasing the stored energy before it can travel through the body column. As you will see, insole materials are not the same in structure or performance!


Heel Strike On Common Foam Cushion Insole Heel Strike On Viscolas® Reliever Insole
Heel Strike
Heel Strike
Heel strike completely compresses the foam insole. Permanent compression and loss of rebound capability begins to take place in the first few days of wear. They completely compress, or bottom out, in just a few weeks. Perspiration, heat and friction cause the foam insoles to break down and crumble, further diminishing their effectiveness. Heel strike is displaced laterally, spreading the energy force evenly over the insole surface providing maximum energy dissipation and storage capabilities. By nature of their material, Viscolas® insoles resist permanent compression and retain their total effectiveness for up to 12 months. Viscolas® is not affected by perspiration, heat, or friction (sole sheer).
