Soft is the first word that comes to mind. These are softer than cotton, yet they're nylon and spandex, generously tailored for men, with an ample, wide top band that will keep these socks up comfortably all day long. With plenty of room to wiggle the toes, they have a wide ribbed pattern with a masculine, dressy look, yet they're as thin as the fine quality women's trouser socks after which we've patterned them. They're almost completely opaque at the ankles, and a bit sheer at the heel and calf, where they're stretched. So we're calling them semi-sheer. Try them once and you'll agree that they're cooler and much more comfortable than traditional heavier and sweatier men's nylon dress socks. These are a real breakthrough in fashion and functionality. Contains 93% nylon and 7% spandex. Available in one size; colors: black, navy, and brown.
