These boots are designed for adult female adventurers. For optimal fit, ensure you try them on with the type of socks you typically wear for hiking. Lacing: Use the lacing system to secure your foot snugly, preventing heel slip without overtightening. To prolong the life of your boots and maintain their performance, especially the GORE-TEX® waterproofing and Vibram® soles, proper care is essential. For cleaning and maintenance, always refer to the specific instructions provided on the product's care label. Generally, GORE-TEX® footwear benefits from regular cleaning with a soft brush and lukewarm water to remove dirt, followed by air drying away from direct heat. Avoid harsh detergents or fabric softeners as they can impair the waterproof membrane. For the leather and synthetic leather components, specific cleaners or conditioners might be recommended by the care label. These boots are compatible with standard hiking sock types and suitable for various hiking activities.
