Using these Merrell athletic training shoes is easy. Just lace them up tightly for a secure fit before you head out for your run or outdoor adventure. When using them for running, you'll notice the responsive support that helps you move quickly. For outdoor activities, the non - slip outsole keeps you stable on uneven ground. As for maintenance, you can use a soft brush and mild soap to clean the mesh upper and synthetic overlays. Let them air dry naturally, away from direct heat. Avoid using harsh chemicals as they may damage the materials. Also, check the outsole regularly for excessive wear. If the laces get frayed, replace them to keep the shoes in good condition.
