Using these Brooks Adrenaline GTS 22 shoes is easy. Just slip them on and you're ready for a road run. They're designed to give you stability and mid - level cushioning. When running, the GUIDERAILS® system will help keep your knees in a safe range of motion. For best results, make sure your feet are dry before putting on the shoes. When it comes to maintenance, you can gently clean the mesh uppers with a soft brush and mild soap. Avoid machine - washing as it might damage the structure. Also, store them in a cool, dry place when not in use to keep the materials in good condition. The heel's HPR Rubber and forefoot's blown rubber are durable, but if you notice excessive wear, it might be time to consider a new pair.
