If you are a cootiephobe like me, you like any gadget that claims to kill cooties (like the ones for toothbrushes, etc,). The SteriShoe makes sense in that it is going after one place that could definitely use some coodie killing, the shoe. The SteriShoe is basically a shoe insert that has an ultraviolet UV light to kill 99.9% of the "problematic microorganisms" in about 45 minutes. This should help stinky feet people (Margaret) eliminate cooties related to foot fungus and chronic shoe funk.
The SteriShoe UV Shoe Sanitizer is available for around $130 here and comes in four sizes.
