The scientific way to rid your shoes of bacteria and leave them with a nice pretty deodorizer after-smell - one of those essential items for your footwear draw!
Smelly shoes are quite simply a result of bacteria in your shoes. Equally, 'simple', material used in the construction affects odor because natural fibers will absorb odor (so that it doesn't get to your nose) whereas synthetic fabrics are not celulose fibers and, inherently, can't absorb anything - this is why they are used to wick moisture after all. Regardless of the fabric, the solution remains the same: get rid of the bacteria.
Except, it turns out that killing bacteria is not simple. You can freeze it to death (yes, put them in the freezer for a few days), you can dous it with Silver shavings (an expensive, but chemically effective, option)...or you could use a product designed to kill bacteria, in Friendly Foot's case, with a PH attack combined with anti-microbial, anti-fungal agents with an aromatic whiff to boot.
Friendly Foot is the highest quality, most effective shoe deodorizer on the market. The powder has a slight acidic value which balances the PH of your shoes, inhibiting bacterial growth. Together with four organic essential oils, FF provides anti-microbial, anti-fungal, anti-bacterial and antiseptic properties.
What does this mean?
Your shoes will never smell again!

USDA Organic Lavender, Tea Tree, Eucalyptus and Peppermint Essential Oil-
All of these essential oils are known for their anti-inflammatory, antifungal, antidepressant, antiseptic, antibacterial, fungicide and antimicrobial properties.
