How to use: Just put on these sneakers like you would with any other pair. The lacing and zipper make it easy to adjust the fit. Note that if you're a size 45, the oversize option will fit you well. When it comes to maintenance, use a soft cloth to wipe off dirt regularly. For more stubborn stains, you can use a mild leather cleaner. Avoid exposing the sneakers to extreme heat or moisture, as this could damage the synthetic leather and micro - suede lining. If you want to keep the insole fresh, you can remove it and air it out from time to time.
