Businesses in the knitted hosiery category make, distribute or sell garments produced by knitting yarn into close-fitting items for the feet and legs. Products commonly include socks, knee-highs, tights, stockings, leg warmers and specialist hosiery. They may use cotton, wool, synthetic fibres or blends, with different weights, lengths, finishes and levels of stretch for everyday wear, work, sport or formal clothing. Manufacturers typically knit the fabric, shape or finish the garments, and add features such as reinforced toes and heels, ribbed cuffs, cushioning or patterned designs. Suppliers and retailers may offer ranges for adults and children, including thermal, school, work and performance socks, as well as compression or support hosiery. Some businesses focus on wholesale supply to shops and clothing brands, while others sell directly to customers; their services may include sizing advice, product selection and supply of coordinated or custom-made ranges.
