Using your New Balance Fresh Foam X 860v13 running shoes is easy. Just adjust the laces to get a customized fit that's comfortable for you. These shoes are great for all kinds of running, whether it's a short jog around the block or a long - distance run. When you're running, the medial post will help control your pronation, so you can have a more stable stride. As for maintenance, it's a good idea to clean your shoes regularly. You can use a soft brush and mild soap to gently clean the upper part. Don't put them in the washing machine as it might damage the structure. Let them air dry away from direct heat. Also, store them in a cool, dry place when you're not using them. Keep in mind that the 10 mm drop is approximate due to manufacturing variances. If you have any foot - related concerns, it's always a good idea to consult a podiatrist, even though these shoes have the APMA Seal of Acceptance.
