Using your Fidelio Multistretch Mitzy is a breeze. Just use the zipper and lace closure to adjust the fit according to your comfort. Put in the removable cork insole if you want extra comfort or full orthotics support. When walking, the air - cushioned sole will make each step feel light. For maintenance, keep your shoes clean by wiping them with a soft cloth regularly. Avoid exposing them to extreme heat or moisture as this can damage the leather linings and the sole. If the insole gets dirty, you can take it out and clean it separately. That's it! Enjoy wearing your stylish and comfortable shoes.
