Machine Wash Our Funny Socks are soft and comfortable with a mesh design that is breathable and moisture wicking. Carefully crafted to avoid the loose knits and frays found on other novelty St Patricks Day socks. Comfortable, high-quality fabrics ensure they can withstand years of wear and washing without fading, while remaining soft. Elastic Structure - Our art St Patricks Day socks have the right tightness, ergonomic product design, and a firm fit. In addition, our crew socks have 20-30 mmhg of compression to promote blood circulation and relieve exercise-induced soreness. Anti-slip Design - What makes our funny socks superior to others is that they are not only fun, but also sporty. The St Patricks Day athletic socks have a threaded design at the bottom, gripping, non-slip, suitable for many sports, such as football, skating, yoga, skateboarding, running, skiing, etc.
