Truform women's trouser socks provide moderate graduated compression to help energize the legs - ideal when sitting or standing for long periods. Microfiber nylon is soft, and cooler to wear than standard nylon. Attractive designer-knit delicate rib pattern makes this sock an excellent choice for business, or business-casual wear. SMOOTH-KNIT FABRIC: The sophisticated, rib pattern fabric is perfect for business or casual wear. The microfiber nylon is soft, cooler to wear than standard nylon, and completely latex free. STAY-UP SOFT TOP: The soft non-compressive, stay-up top was carefully designed for wearing comfort. The flexible but snug fit ensures the stocking remains in place throughout the day without constricting the leg. KNIT-IN HEEL: Knit-in, defined, reinforced heel pocket provides added durability and easy stocking orientation on the foot and leg for a proper, comfortable fit. CLOSED TOE BOX: The roomy toe box applies no compression to the wearers’ toes ensuring a comfortable and natural fit. The reinforced fabric protects against one of the most common areas prone to wear and tear.
