Welli-Top is an ingenious invention that everyone with a pair of wellies should have. Simply clip it on to the top of your wellies to stop rain getting inside & deter all those pesky little insects & spiders from making homes in there. It also helps keep boots upright & in pairs so they won't become damaged at the ankles & makes it easy to hose dirty boots down as well. The handy cord makes it a doddle to hang wellies up in the garage or storage area. Welli-Top fits all sizes.
