Using these New Balance 1080V13 running shoes is straightforward. Just lace them up and start your run or daily activities. When it comes to sizing, keep in mind that the 6 mm drop is an approximate value. If you have a specific need for cushioning, the soft midsole will give you great support. For maintenance, you can clean the shoes with a damp cloth. Avoid using harsh chemicals as they might damage the engineered mesh upper or the midsole material. Also, don't leave the shoes in direct sunlight for too long, as it could fade the color and affect the shoe's structure. Store them in a cool, dry place when not in use. These shoes are suitable for various activities, but if you're doing high - impact sports, make sure to check the wear on the outsole regularly and replace the shoes when needed.
