Keen is launching an intensive consumer-testing program this summer on the Pacific Crest Trail (PCT) to demonstrate the durability of its Olympus hiking socks. The PCT stretches from southern California to Canada, with elevations ranging from sea level to more than 13,000 feet. The route crosses 25 national forests and seven nation parks. With an average 20-mile hike each day for up to six months, Keen's PCT Olympus ambassadors will put their socks through extremely tough conditions, which the company considers to be ideal for the test. Throughout their journeys, the ambassadors will send technical information on the performance of the socks back to the Keen product team. They will also constantly update their own blogs about their adventures on the trail. Fans can follow the Olympus PCT ambassadors on social media with the hashtag #OlympusPCT. The body of Keen's Olympus sock is made of moisture-wicking, non-itch merino wool while the toe and heel are reinforced with Dura-Zone, which contains a strong patented fiber. Each Keen Olympus sock comes with a “guaranteed for life” warranty.
