These Josef Seibel booties are super easy to use. Just unzip the inside zipper, use the heel pull tab to slide your foot in, and then adjust the laces for a perfect fit. When it comes to cleaning, use a soft, damp cloth to wipe off any dirt on the full - grain leather. Avoid using harsh chemicals as they may damage the leather. For the wool - polyester blend lining, you can spot - clean it gently. Store the booties in a cool, dry place when not in use. The removable padded footbed can be taken out and aired occasionally to keep it fresh.
