|This compact and
lightweight PVC sole is the most abrasion resistant type
of PVC sole.
PVC sole consists of a highly abrasion-resistant ground contact
area using compact PVC, and a middle layer using thick, highly
impact absorptive PVC foam. It is also lightweight.
||This extremely abrasion
resistant urethane foam sole minimizes the amount of dust
raised by abrasion. The thick, cushioning sole prevents your
feet from getting tired.
outer sole is made of high-density urethane foam with an
abrasion rate approximately 9.7% lower than that of the conventional
single-layer sole. Well-cushioned, low-density urethane foam
is used for the middle layer of the sole.
