Using these shoes is as easy as it gets. Just slip them on or lace them up depending on your preference. When choosing a size, don't forget to measure your foot length from heel to toe and match it with our size guide. These are standard EU leather shoe sizes, not like sports shoes. If you're not sure, reach out to customer service. For maintenance, keep them away from sharp objects to avoid scratching the leather. Clean them regularly with a soft cloth. You can also use a leather conditioner every once in a while to keep the leather looking new and supple. Store them in a cool, dry place when not in use to maintain their shape and quality.
