Footwear providing enhanced protection against extreme landing impacts
includes a sole having an elastomeric mid-sole with elastomeric pads
combined in a heel recess thereof such that the pads act in series with
each other and in parallel with the mid-sole during conjoint compression
thereof. At least one of the pads includes a solid gel having a
relatively high damping coefficient. In another embodiment, the heel of
the mid-sole is replaced by a toroidal gas cushion and an elastomeric pad
including a solid gel having a relatively high damping coefficient
disposed in a central recess of the cushion such that the pad is recessed
a selected distance below the upper surface of the cushion. The resilient
pads may advantageously incorporate a plurality of gas-filled cells, and
a solid gel pad may also be disposed in the mid-sole of the footwear
below the ball of the wearer's foot for increased protection.
