Excellent 2-pack value with one pair in the color Charcoal combo, and a second pair in the color Khaki combo - Our socks are produced on the most modern equipment in the world, giving us access to every conceivable feature that can be incorporated in a sock. Spandex Throughout — All Goodhew socks are manufactured with Spandex throughout the entire sock. One of our complaints about so many socks is "bagging out" of the sock as the day goes along. Spandex used throughout the entire sock ensures a snug fit all day long and helps prevent slipping in the shoe. We are not aware of any other brand that uses spandex throughout the sock in every sock they make. Flat Toe Seams — There is probably no greater item that can cause discomfort in a sock than a bulky toe seam. We use specially developed flat toe seams in all of our socks to ensure that you don"t even notice they are there. Arch Support — An arch support is an added band of spandex that is knit into the sock in the arch area of the foot. An arch support serves two functions: providing support to the arch area of the foot and reducing slipping of the sock on the foot. Ring Toe Cushioning — We use ring toe cushioning in all of our cushioned socks. Ring toe cushioning is an extra band of cushion we put around the toe seam of the sock to bury the toe seam and further enhances the comfort of our flat toe seams.
