I bought an electric Shoe dryer for me unknown company LUCOG working from the usual outlets 220 Volts. Below I have described the pros and cons in my opinion, and bought on Aliexpress here on this page.
At any time of the year — what you need. Heat gradually over 5 minutes up to 65-80C. Dried well, since quite long, 19.5 cm
These dryers have 2 heating electric element, which contributes to uniform heating of the entire surface of the dryer and not just parts of it, consequently the shoes will be dried fully, and not, say, just in the middle.
Thanks to the two wires (each for 48 to see their connection), the dryer will fit in any Shoe, even high boots.
In total, the entire wire as a whole is quite long — see 153 For the safety of these dryers don’t have to worry, personally I leave the shoes to dry overnight and do not burned, not broken.
In the beginning of use, when heated, had a little smell of plastic, but over time disappeared. Also the disadvantages include the flat plug, but this disadvantage is offset by the adapter that comes in the kit.
