100% Waterproof, Breathable, and so Much More... The Wudhu Socks are so much more than 100% waterproof and breathable socks. Our three-layer technology makes them super comfortable and extremely durable. How do we know? We walked three miles in them without shoes and they were as good as new! This 3-mile test was a necessary condition for being given a fatwa that guarantees The Wudhu Socks are 100% Shari’ah compliant.
