Not just another white sock. USA-made acrylic fibers are interwoven with ultra-soft cotton body yarns, and the high-bulk acrylic footbed resists compression so the cushion lasts all day. That cushion extends over the top of the foot, which is what makes it work in steel toe boots. Reinforced heel, toe and footbed for long-term durability, a comfort toe seam that prevents chafing, and a stay-up comfort top that won't slip down during a long shift. Crew height, perfect for 6" work boots. Made in Niota, Tennessee.
