【Used Once】O'NEILL MUTANT4 FIREWALL Round Toe Type (AFW830A2) 2022-2023FW Model Used: Once A highly recommended Mutant boot with a round toe for increased warmth and water resistance. The inner lining uses FIREWALL 27, a stretchable, heat-generating brushed material. It offers excellent heat retention and flexibility, doesn't hinder subtle trimming during riding, and features a Japanese foot shape for a good fit. The 5mm thickness on the instep and 4mm on the heel make it easy to put on and take off. The rubber section and the transition near the arch gently hold the entire foot, without interfering with subtle trimming. Material: 5/4mm thick Ultra Flex Cryptojersey / FIREWALL 27, Rubber Sole Size: My shoe size is 27.5cm Color: Black #Surfing #SurfBoots #ONeill #Mutant #MUTANT_BOOT #WinterSurfGear #ONEILL #O'Neill
