While you wouldn't want the ill-fitting slouch of actual retro socks, the Giordana Sport Socks are a different story. They look old school, and indeed are made with 25% wool, the most old-school of high-tech materials, but Giordana also integrates a whole bunch of PrimaLoft, nylon, and Spandex into the mix for a stretchy, soft feel that stays warm and helps manage moisture at the same time.
