Using these Rocky Sport Pro Rubber boots is a breeze. Just slip them on like you would with any regular boots and start your outdoor activities. Whether you're hunting or just walking in wet areas, they'll keep your feet dry and warm. When it comes to maintenance, after each use, clean off any dirt or mud with a damp cloth. Let them air - dry naturally; avoid using direct heat sources as it can damage the rubber. Also, check the removable PU cushion footbed regularly. If it gets dirty, you can take it out and wash it gently. Keep in mind that the shaft height and circumference can vary by size, so make sure to choose the right fit for you. And be aware that the weight of 4.9 pounds per pair is for a size 10, which might be a bit heavy, so get used to it gradually if you're not used to heavy boots.
