Protect the integrity of a crime scene with the ingenious, easy-to-use Step N Go. Simply step in and out of the Step N Go and a protective plastic covering will automatically be placed over your shoe or foot. That means no hassles, bending over, or wasting time trying to get the plastic covering on, it's as simple as “step in and step out”. The elastic strap will keep the protective coverings snuggly on any foot or shoe, which will allow you to move throughout any crime scene without the danger of contamination from your shoes. The disposable coverings can also be easily removed and discarded or saved for examination. The Step N Go comes complete with 100 disposable shoe covers. Additional packs of 100 shoe covers can be purchased as well.
