High-quality boots are always expensive, and you may need some basic advice on how to get the most for your money.
Once a month, rub the outside with shoe lotion or conditioner. If the inside of the boots is leather, too, apply lotion and wait until it is fully absorbed before you wear them again.
Replace heels when the grind down or the edges are uneven. If the heel cap comes off, get it replaced right away, otherwise the heel will wear down very quickly.
When you buy a new pair of boots, it might be a good idea to have a shoe repair shop put a thin rubber half-sole on the bottom. It will prevent the sole from early wearing down, as well as boost the water-proof effect and keep your feet warm.
