I recently picked up a gym membership and starting running on the treadmill regularly. Already I’ve spent money on new running shoes, moisture wicking socks, blister tape and athlete’s food spray. And while I’m resistant to spend any more money, there is apparently one more purchase I can make that will protect my feet and my shoes. SteriShoe UV Shoe Sanitizer kills germs that cause athlete’s foot, nail fungus and shoe odor. That means no more itching feet and no more leaving my running shoes on the porch over night to escape the stench—and you really can’t put a price on that.
