Wear the Volas Waterproof Non-Slip PVC Shoe Covers on outdoor ground that is wet or slick, over the shoes you already have.
The page pairs waterproof protection with anti-slip grip and outdoor use. It does not name workplaces, sports or a certified safety rating. Do not treat them as listed safety footwear.
They are less useful indoors, or if the cover cannot fit the shoe, because no size selector is listed.
Pick Blue or White on the Volas shoe cover page.
