A shock-absorbing system and device for footwear, and a footwear article including
the device. The shock-absorbing device has a plurality of first projections distributed
on and extending upwardly from the upper surface in contact with the user's foot,
and a plurality of second projections distributed on and extending downwardly from
the lower surface in contact with the ground. During the flexion of the foot when
stepping, the second projections yield elastically, and displace the first projections
upwards and into contact with the foot. The first projections move in a plurality
of directions, achieving a massage action, the shock-absorbing, and the uniform
distribution of the load on the foot.
