Neoprene WARM MAX ankle support. Supports against the cold of muscles, etc., during warm-ups and matches. Made of neoprene material, so the fit is outstanding. Neoprene is a material made from foamed synthetic rubber called chloroprene. It has excellent heat resistance, cold resistance, water resistance, weather resistance, and cushioning properties, and is used in a wide range of products such as wetsuits, PC protection cases, and bags. Size is M. There is no distinction between left and right. The size tag is missing. It is old, so there are scratches and damage. Please consider purchasing only if you understand this. Please refrain from purchasing if you are sensitive to such things. - Brand: WARM MAX - Color: Black - Type: Foot cover, supporter - Material: Neoprene #Supporter #Ankle #Foot #FootSupporter #ForWinter #WarmingUp Thank you for viewing.
