4 Paw Eco Dryer FORCES HEATED AIR INTO BOOTS, GLOVES, AND SHOES  The Outdoorsmans portable boot, glove, and shoe dryer works by directing air from your floor vent up into four plastic tube attachments on which you can place your wet footwear and handwear. Drying times vary depending on the dampness of your footwear and handwear and the cycle time and temperature of your air vent system. GO GREEN WITH THIS NON-ELECTRIC ECO-DRYER  This boot, glove, and shoe dryer is non-electric and thus eco-friendly. It is adaptable to whatever heating and air conditioning system is in place in your home or apartment, requiring no additional energy. You dont need to worry about any cables or risks associated with the combination of water and electrical dryers. ADJUST POSITION ON VENT TO REGULATE AIRFLOW  To regulate the amount of air and heat blown into your boots, shoes, and gloves, simply adjust the position of the dryer base so it is partially or fully covering the floor vent. You can also make adjustments by opening or closing your floor vent. You may want to use less air if you are only warming your footwear and handwear. DRIP TRAY CATCHES EXCESS WATER AND DIRT  The base of this boot, glove, and shoe dryer is equipped with a convenient drip tray that will catch any excess water and dirt as it falls from your footwear and handwear. Dry your snow boots, rain boots, work boots, ski gloves, running shoes, etc. without making a big mess or using a tumble dryer. EXTENDABLE FOR TALL BOOTS  This eco-friendly boot, glove, and shoe dryer comes with five parts, including a base and four airflow tubes. Our innovative design allows you to stack one airflow tube over another to increase the height of the tubes. This convenient feature makes the dryer compatible with taller footwear like rubber rain boots and western/cowboy boots.
