Designed exclusively for use when stripping floors. They are meant to be worn on flat surfaces only. Do not use on stairs. The TensionFit™ upper is made to last through multiple jobs. The replaceable pads are intended to be cleaned at the end of each use to increase their longevity. The StripGrip pads are easily placed into the Retention Band System™ to ensure the pad doesn't fall off, like it does with velcro pads. The cushioning that the upper and pad provide helps reduce leg fatigue for operators who are on their feet all day. No slipping results in much less muscle tension, so the wearer is more comfortable and productive. Only use Stabil Strip GripsPads on this product.
