A nod to a classic fly-fishing technique and Scotland's legendary River Spey, the Spey Fly sock draws its inspiration from Darn Tough's own fly-fishing guru and Mill patriarch, Marc Cabot — the real deal. This lightweight lifestyle sock is too. Silky soft Merino Wool, terry loop cushioning underfoot, and arch support that keeps everything comfortably in place make it as capable as it is classic. You may never reel in stream dolphins like Marc does, but you can sport the same socks.
