To use these boots, simply zip them up using the inside zip closure. They're designed to fit true to size, so you can choose your regular shoe size. When wearing them, be careful on slippery surfaces due to the high heel. To maintain them, keep them away from sharp objects to avoid damaging the clear vinyl or the marabou fur fringe. You can clean the vinyl with a soft, damp cloth. Store them in a cool, dry place when not in use to keep them in good condition.
