It's imperative to dry shoes after washing or wearing to inhibit the growth of bacteria and odors, so 'DRYSUREs' are designed to aid this effort. Coming in a variety of different sizes and shapes, the 'DRYSURE' shoe dryers work by being inserted into footwear after a long day of wear or after washing. The silica oxide beads within the units absorb moisture in a flash to make drying out footwear easier and faster than ever.
After using a pair of 'DRYSUREs,' the products will need to be dried out themselves, which can be done by popping them into the oven on a low heat for about an hour.
'DRYSUREs' make dry shoes a constant for athletes and active individuals who aren't fans of slipping on moisture footwear.
