The average pair of feet has about 250,000 sweat glands and can produce a pint of sweat a day. This sweat is a breeding ground for bacteria. Purra solves this problem with their proprietary antimicrobial technology that inhibits the growth of bacteria, germs, microbes and fungi, keeping feet clean, fresh and odor-free.

Foot odor is directly related to bacteria on your skin. When you sweat, the moisture creates an ideal environment for bacteria to thrive. These bacteria break down sweat and dead skin cells, releasing unpleasant odors as a byproduct.  Purra solves this problem with their proprietary antimicrobial technology that inhibits the growth of bacteria, germs, microbes and fungi, keeping feet clean, fresh and odor-free.

Zinc. Purra uses Copptech, an EPA-registered safe, natural zinc antimicrobial. Zinc is a natural element. It’s in multivitamins, lotions, shampoo, food, and even your blood. Zinc is also a major player in the creation of DNA, the growth of cells, building proteins, the healing of damaged tissue, and supporting a healthy immune system.

Since every shoe has different shapes, Purra insoles are available in full sizes from US 4 to 13 and are strategically designed to be easily trimmed (instructions included) to fit any shoe style, from running to dress shoes. Enjoy unlimited versatility with your favorite footwear.
