I saw this last year but didn't buy one- kicks self in bum...
A shoes rack, but it plugs into mains and heats up to warm/dry shoes.
I think it held 6 pairs of shoes and was about 2.6' wide.
I've got a shoes rack in the porch but this would be ideal to dry off the DC shoes or just warm them up ( porch gets cold in winter) I usually put shoes on radiator for a while but its not good for them. And they fall off 
Where can I get one. Does anyone have one? Would you recommend?
