These Brooks Men's Beast 20 running shoes are great for both walking and road running. To use them, simply lace them up and start your workout. For best results, make sure the laces are adjusted to fit your feet comfortably. When it comes to maintenance, clean them regularly with a soft brush and mild soap to keep the engineered air mesh upper looking good. Avoid exposing them to extreme heat or cold, as this can damage the materials. Also, if you notice any signs of wear on the HPR Plus abrasion - resistant rubber outsole, it might be time to consider getting a new pair. And remember, these shoes are designed for flat and medium arches, so make sure they suit your foot type.
