To use these boots, first adjust the hook and loop strap and toggle collar to get a snug fit. Then, use the heel pull strap to easily slide your feet in. These boots are great for cold and wet days, like winter hikes or snowy commutes. When it comes to maintenance, after using them in mud or snow, let them dry naturally at room temperature. Avoid using a heater or direct sunlight as it can damage the materials. You can clean the waterproof rubber shell with a damp cloth. If the removable EVA insole gets dirty, take it out and wash it gently with mild soap and water. Make sure to let it dry completely before putting it back in the boots. Keep these tips in mind, and your boots will last a long time.
