Product Overview<\/strong><\/span><\/h2>\n

C4 Carbon 0.5mm open heel sock<\/strong> is an ultra-thin, high-performance sock designed for freediving and spearfishing where sensitivity, comfort, and precision matter the most. Built specifically for use with open heel fin systems<\/strong>, it delivers a direct connection between your foot and the fin, improving control and efficiency during every kick.<\/p>\n

Made from 0.5 mm pre-compressed neoprene<\/strong>, this sock offers minimal thickness while maintaining durability and comfort. The reduced material thickness allows maximum sensitivity, so you can feel every movement of the blade and maintain precise control underwater.<\/p>\n

The outer surface features a smooth finish to reduce wear, while the inner lining ensures easy donning and long-lasting comfort. Additionally, internal reinforcement increases durability in high-stress areas, making the sock suitable for frequent and demanding use.<\/p>\n

        • better control during finning<\/li>\n
        • more natural movement<\/li>\n
        • reduced energy loss<\/li>\n
        • improved kicking technique<\/li>\n<\/ul>\n

          At the same time, the reinforced construction ensures the sock remains durable even under repeated use with tight foot pockets.<\/p>\n
