The knee pads have multi-layer memory foam inserts that mold and protect the knees, and they also have side padding for additional protection. The fully opening design means there is no need to remove your shoe. These knee pads are highly abrasion resistant and feature impact panels with a graphic design. They are secured in place with wide elastic Velcro straps, which have easy-grab griptabs. The knee pads have a terry lining for additional comfort and moisture control.
