To use these Haflinger AT shoes, simply slip your feet in. They're designed to fit comfortably right away. When it comes to the weather, you don't have to worry - they'll keep you warm in winter and cool in summer. For everyday use, you can wear them casually or for short walks. As for maintenance, try to keep them dry. If they get wet, let them air dry naturally. Don't put them in a dryer as it might damage the wool. You can use a soft brush to gently clean off any dirt on the surface. Also, store them in a cool and dry place when you're not using them. If you notice the arch support isn't as good over time, it might be a sign to replace the shoes. Enjoy your comfortable and stylish Haflinger AT shoes!
