The Canarie LT 2 mm is 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 underwater and 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.
