As you can see, Poron® has the lowest "g" rating on the Peak Deceleration Scale. The lower the rating on this scale indicates how great the shock reduction of the material is when under pressure.

Poron® retains "like new" softness, will not shrink, or become brittle. It will not bottom out, but returns to its original shape with each step. This results in maximum foot comfort by reinforcing the structural heart of the shoe.
