You may have seen the wacky commercial for Invisisox, the socks that claim to fit so well, they won’t slip off even when being pulled by a pickup truck.

Inside Edition’s Steven Fabian put the commercial’s claim to the test, and enlisted the help of a Princeton engineering professor, a stuntman and a professional driver to see if they could knock Steven’s socks off. #InsideEdition
