Introducing Nike's newest running socks. Designed to give you a locked-in fit, they feature sweat-wicking wool fabric and strategically placed cushioning and support. This means you can forget the fit and focus on your miles. Stay Dry:Nike Dri-FIT ADV technology combines moisture-wicking fabric with advanced engineering and features to help you stay dry and comfortable.
