Protective outerwear designed to fit over existing footwear, providing insulation and weatherproofing against low temperatures, snow, and ice, typically made from waterproof and insulated materials like neoprene, nylon, or rubber. Examples include lightweight, slip-on versions for short-term exposure and heavy-duty gaiters for extended use in extreme conditions.
Maintaining foot warmth and dryness in cold climates is crucial for comfort and safety, preventing cold-related injuries such as frostbite and hypothermia. This type of footwear protection offers a practical solution by adding an extra layer of insulation and defense against the elements, extending the usability of existing boots in challenging conditions. Historically, similar protective measures have been employed using readily available materials like animal hides and woven fabrics to safeguard against harsh weather.
