To use these boots, simply lace them up and adjust the tightness according to your comfort. You can wear them in various weather conditions, but it's best to avoid wearing them in heavy rain for long periods. When it comes to maintenance, clean the boots regularly with a soft cloth. For the leather parts, you can use a leather cleaner and conditioner to keep them looking new. As for the footbed, you can remove it and wash it gently with mild soap and water. Let it air dry completely before putting it back in the boots. Also, store the boots in a cool, dry place when not in use to prevent damage.
