How to use: Slip your feet into the shoes. If you want quick and easy on - and - off, use the speed - lacing system. Just pull the laces tight and you're good to go. If you prefer the traditional way, you can use the classic laces that come in the box. Tie them up like you normally would. Note: These shoes are designed for running and light exercise. Don't use them for heavy - duty work or extreme sports. Maintenance: After a run, let the shoes air dry. Don't put them in a dryer as it can damage the materials. You can gently clean the shoes with a damp cloth and mild soap. Keep them in a cool, dry place when not in use.
