Filter the Air as You Walk in a Sock. Do you need to be stylish, comfortable and environmentally conscious? If so, then welcome to your new socks. DAMN Filters Eco Filtering Socks. Amazing Technology and Theoretically Possible. Just think of them as eye-catching cartridge filters attached to your legs. Not only will you look like a million bucks but our Eco Filtering Socks can tackle air particulate down to nearly 0.001% efficiency @ 0.3 centimeters. via GIPHY Our special blend of engineered filter media uses the magic 60/22/19 formula (60% Nylon, 22% Cotton, 18% Spandex) for foot comfort. We then weave these materials together in a "criss-cross" pattern to form a tortuous path of potential filtration that can easily be applied to the lower legs and feet. Medium to large air-contaminants are no match for our socks. Insects, airborne organics, and large pieces of dirt and gravel were captured, or deflected outright, by the filter surface. In repeated computer models we were able to prove a statistically detectable amount of particulate is captured from the air when wearing these socks and vigorously moving about the room for several hours. Quiet those barking dogs. Filter Media Sizing Guide M L XL US men 6-8 8-12 12-15 US women 8-10 10-14 14-17 EU 39-41 41-46 46-49 UK (inches) 6-7 ½ 7 ½-12 12-14 ½
