To use the Men's Merrell Vapor Glove 6, simply put them on like you would any other shoes and start your trail running or training. These shoes are great for getting a bare - foot like experience during your activities. When it comes to maintenance, clean them regularly. You can use a soft brush and mild soap to gently clean the mesh upper and the outsole. After cleaning, let them air dry. Avoid putting them in the dryer as it might damage the materials. Also, be careful on rough terrains as the minimalist design means they may not provide as much protection as regular shoes. If you notice any signs of wear and tear, it might be time to replace them to keep performing at your best.
