AutoSock were developed in Norway over 15 years ago, and have been tested and approved both by the German TÜV and by most car manufacturers, including BMW Group, Citroën, Fiat Group, Honda, Hyundai, Jaguar, Land Rover, Lexus, Mazda, Peugeot PSA, Mercedes-Benz, Nissan, Subaru, Toyota, and VW Group.

There are many copies and knock offs; several of these are being sued for breach of patent. AutoSock will not be the cheapest because the specially developed polyester is made in Germany, and the factory that makes them is approved to international quality and welfare standards, including ISO 14001, ISO 9001, OHSAS 18001. They are also fully tested by TÜV SÜD against the very high criteria developed by TÜV, AutoSock, and a leading vehicle manufacturer; no other snow socks have passed this standard. AutoSock do of course also have full product liability insurance, and all these certificates can be exhibited on request.
