1. It can heat up relatively quickly, taking about 15 seconds, and features 360-degree circulating constant-temperature heating. With this constant-temperature heating, it is less likely to burn, deform or damage shoes. It is not recommended to directly dry dripping shoes. 2. It is made of ABS + PC materials, which are resistant to pressure, high temperatures, and are fireproof and flame-retardant. 3. It has double-sided porous heat dissipation, and the circulating heat dissipation effect of hot air is relatively good. There are multiple heat dissipation holes densely distributed on both sides of the fuselage. When heating, a circulating heat flow is formed in the shoe space, covering both the sole and the upper. Even the hard - to - reach areas can be dried relatively evenly. 4. It can be used throughout the year. Whether it is winter snow boots or summer thin socks, it can dry them. 5. Product colors include white, pink, and blue.
