>>968216>But why not just use regular socks?It really depends on the sock type and environment you are getting your feet wet. Sand chafes madly. Any socks will be better than no socks. Socks that keep sand out are best. Socks are intended to take on the slippage of the footwear on the outside of the sock and stick to your skin without moving across the skin. Any sock movement across your skin can result in a blister.
Normal, everyday socks react differently when they are wet. Some tighten up in places and loosen in others. A loose section will slip across the skin as you walk and start a blister. Socks designed for underwater use and waterproof socks are normally made form materials that do not loosen up while wet.
