These split toe neoprene socks from Orca provide maximum thermal insulation to your feet. And thanks to their fit, they stay put and will not bother you while swimming. Features: - Extra Warmth: The Thermal X thermal lining provides added warmth, helping to trap heat and avoid heat loss throughout your workout. - The pattern with a separated toe improves the fit, allowing the hydro booties to stay in place, thus preventing water from entering. In addition, the soft thermal lining provides added comfort and prevents chafing on the skin.**This accessory should be worn under a neoprene wetsuit to minimise water entry.
