Acrylic is cheaper than merino wool and is a versatile fabric. It is comfortable, provides good cushioning, and dries fairly quickly, which makes acrylic socks more comfortable.
Acrylic is a lightweight man-made synthetic fiber, known for its softness and high durability. It provides good cushioning and excellent friction and moisture management.
