Using these Merrell snow boots is a breeze. Just put them on like you would with any regular boots and you're ready to take on winter activities. When using them for winter hiking, make sure the laces are properly tightened for a secure fit. For snow shoveling, the boots' traction will help you stay steady on slippery surfaces. As for maintenance, after each use, clean off any dirt or snow with a soft brush or cloth. If they get wet, let them dry naturally in a well - ventilated area, away from direct heat sources. Avoid using harsh chemicals to clean them as it may damage the materials. With proper care, these boots will serve you well for many winters to come.
