To use these Naot Norther boots, simply unzip the side zipper and slide your feet in. Zip it up when you're ready to go. When it comes to maintenance, use a soft cloth to wipe off dirt regularly. You can also apply a leather conditioner every few months to keep the black leather looking its best. Avoid wearing them in extreme weather conditions like heavy rain or snow to prevent damage. And don't forget to remove the footbed occasionally to air it out for better freshness.
