If you are tired of wet boots you can actually make a boot dryer yourself.
You probably know that leather shoes and boots should not dry at the heating devices. They should dry at room temperature. So we are not going to heat, we are going to ventilate.
What can be boots ventilated by from inside? With low-power fans. CPU cooler ones are perfect for that! If you don't have any, they are quite cheap. By the way, some are even illuminated.
Those we are going to use have power of 12 volts.
They are a bit different, but it doesn't matter.
