The Canarie socks are designed with left and right feet to fit every curve and bend with each foot movement. The Premium Ultra-stretch Neoprene will be your “second foot,” lined with elastic nylon. Ideal for keeping your feet warm under water and in preventing any abrasion caused by extensive training, rocks, or jellyfish. These are the only soft-soled neoprene socks you'll ever need for Spearfishing, Freediving, Surfing, Canyoneering, Watercraft, or any water sports you want to practice. The Canarie ST 2mm is designed in Italy by Cressi and made in China. Cressi has been an Italian brand pioneer in scuba diving, freediving, and snorkeling equipment since 1946. The product is covered by a 2-year limited warranty.
