4 Pair DuPont XL Boot Cover IsoClean Tyvek IC447SWHXL0100CS 30J233 Exp 5/25
They are made from Tyvek IsoClean material and are a size XL. The picture shows one on my leg. I wear a size 12 wide shoe and had no difficulty putting it on over an athletic shoe. They could be used in HVAC, plumbing, residential electrical servicing, painting, drywall, etc.
