Hiking boots are footwear specifically designed for hiking. They are one of the most important items of hiking gear, since their quality and durability can determine a hiker's ability to move far, fast, and safely. Hiking boots are constructed to provide comfort for walking considerable distance over rough terrain, and protect the hiker's feet against water, mud, rocks, etc. Heavy boots with soles with a thick sole and heel are recommended. Hiking boots give ankle support and are fairly stiff. A less popular alternative is to use light trainers with thin soles so that the ground is felt and missteps avoided. Footwear should be neither too loose or too tight, to help prevent blisters and sore feet. Hiking socks that wick sweat from the feet, provide warmth, and cushion the feet are recommended and a thin, inner sock may also help. Most hiking boots are also designed for other outdoor activities such as backpacking, climbing, mountaineering, and hunting.
