How It Works

About UVC

The SteriShoe sanitizer destroys microorganisms in shoes with its germicidal UVC lamp. UVC has been used as a germicide for decades in hospitals and water treatment systems. We often hear about UVA and UVB; this is the wavelength of light that gives us suntans and sunburns. UVC is completely filtered by our atmosphere and that is why we do not hear about it often. However, within scientific communities and medical communities, UVC’s ability to destroy microorganisms is well known and established.

UVC works when microorganisms are directly exposed to UVC light. Plastic blocks UVC from reaching the microorganism. Unlike an “As Seen On TV” product that claims to use UV inside a shoe, the SteriShoe sanitizer’s UVC light effectively treats the inside of a shoe because it is not blocked by plastic.

Why not a spray or powder?

Chemicals in a shoe! Do you want to bathe your feet in chemicals?

Once you add a spray or powder to a shoe there is no way to get it out. If you think that allowing the chemical to “dry out” makes an effective option, keep in mind that the sweat from your feet will reconstitute the chemicals and this creates a chemical bath for your feet. Also:

  • There is no data for any chemical being used to treat a shoe.
  • Chemicals are toxic! The most popular household disinfectant says “do not use on clothing or in direct contact with skin.” Other sprays and powders state “not for application on the human body” and “use in a well ventilated area.” Some of these products use formalin – the same chemical known to cause cancer and is used to preserve specimens.
  • How much of a chemical should you use and would you use it daily if you need to seal it in a bag for 48 hours?

The SteriShoe sanitizer adds nothing to the shoe. Its UVC is a controlled dose so shoes are properly sanitized after every 45 minute treatment. The SteriShoe sanitizer automatically turns itself off after a full treatment, and then you are ready to go. No further drying time and no worry about what’s left behind. You can use it daily or even multiple times throughout the day.

How to use it

how-to-useWhen you take off your shoes you can insert the SteriShoe sanitizer into your shoes as you would insert a normal shoe tree. A simple press of a button starts a 45 minute treatment cycle. After 45 minutes up to 99.9% of the harmful microbes that can cause toenail fungus, athlete’s foot and offensive shoe odor are destroyed.


UVC light is a powerful germicide. To prevent people from coming in direct contact with UVC light, the SteriShoesanitizer includes several safety features, a compression sensor and an ambient light sensor. The compression sensor requires that the SteriShoe ultraviolet shoe sanitizer be in a shoe and slightly compressed. If the SteriShoe sanitizer is treating a shoe and it is removed from the shoe, the compression sensor will shut the UVC light off. The ambient light sensor pre-scans the shoe before allowing the SteriShoe shoe sanitizer to turn on. If the ambient light sensor detects a dark environment, the SteriShoe shoe sanitizer will turn on; however, if enough light is detected it will not turn on.

(Note: two shoe bags are provided with every purchase so a user can cover their open-toed shoes and sandals to provide a dark environment for the SteriShoe shoe sanitizer.)
