AW Style 128 Men's Microfiber/Cotton Knee High Dress Socks offer 20-30 mmHg firm compression, and is knitted from a blend of ultra-soft microfiber nylon and cotton-covered Spandex. This provides a comfortable, somewhat cooler sock, with a rich looking microfiber nylon exterior. We've added a subtle pinstripe pattern for a touch of distinctive elegance. Very comfortable and attractive, at a great low price.
