Using these Merrell women's winter boots is a breeze. Just use the inside zipper for quick on and off, and then adjust the traditional lace closure with metal hooks for a snug fit. When you're out hiking in winter, these boots are great for various terrains, especially wet ice, thanks to the Vibram® Arctic Grip™ All Terrain outsole. For maintenance, make sure to clean the boots after each use. You can use a soft brush to remove dirt and debris. If they get wet, let them dry naturally at room temperature, away from direct heat sources as this can damage the materials. Also, periodically check the laces and zippers for any signs of wear and tear. And don't forget to remove the Kinetic Fit™ BASE removable contoured insole occasionally to let it air out. This will keep your boots in good condition and ready for your next winter adventure.
