To use these Fly London YEAY387FLY women's shoes, simply slide your feet in through the opening. The elasticated strap will adjust to your foot for a comfortable fit. When walking, the high platform will give you a bit of extra height. As for care, keep them away from sharp objects to avoid damaging the man - made upper. You can clean them with a soft, damp cloth and mild soap. Store them in a cool, dry place when not in use. Remember, the measurements may vary by size, so if you're unsure, it's best to check the size chart. Also, the weight given is for a single shoe, not a pair.
