What Our Gearhead® Experts Are Saying: "I keep a pair of NATURALDRY inserts in my ski boots after every session. They’re low effort, smell great, and work overnight without needing power—perfect for hut trips or van life."Sometimes the best tech is the most natural. The Hotronic NATURALDRY boot dryer takes a refreshingly simple approach to drying and deodorizing footwear, using 100% natural stone pine filling to absorb moisture, reduce odor, and leave behind a subtle alpine scent. No plugs, no batteries—just pure, passive performance.
