Using these boots is a breeze. Just unzip the back zipper, slip your kid's feet in, and zip it up. When your child's feet grow, you can easily remove the detachable layer of the insole to gain a half - size. As for maintenance, use a soft cloth to wipe off dirt regularly. Avoid getting the boots wet for long periods as it might damage the leather. If they do get wet, let them dry naturally away from direct heat. And don't forget to measure your child's feet every few months to see if it's time to use the insole's growth feature.
