Some<unk> s are worn as safety equipment, such as steel-toe boots which are required footwear at industrial worksites. Additionally, fashion has often dictated many design elements, such as whether<unk> s have very high heels or flat ones. Contemporary footwear varies widely in style, complexity and cost. Basic sandals may consist of only a thin sole and simple strap and be sold for a low cost. High fashion<unk> s made by famous designers may be made of expensive materials, use complex construction and sell for large sums of money. Some<unk> s are designed for specific purposes, such as boots designed specifically for mountaineering or skiing, while others have more generalized usage such as sneakers which have transformed from a special purpose sport<unk>  into a general use<unk> . Traditionally,<unk> s have been made from leather, wood or canvas, but are increasingly being made from rubber, plastics, and other petrochemical-derived materials.
