Legwarmers have been used for decades to warm up legs in colder climates. They are commonly worn by dancers, athletes, and casual wearers. Legwarmers can be made from wool, cotton, or synthetic blends, and come in various lengths and colors. Some popular synonyms for legwarmers include leg sleeves, leg heaters, leg covers, leg cozies, and leg cuffs. While legwarmers were popularized in the 1980s as a fashion accessory, they maintain their practical use in cold weather today. Regardless of what you call them, legwarmers are a cozy and stylish way to keep legs warm.
