In a better world a Swiss Army sock would have files, toenail clippers, a foot powder dispenser and a variety of other foot and shoe-care tools built in. Instead this one is made of a new blend of wool and nylon that is supposedly highly sweat and blister resistant. In recent tests sixty recruits wore mismatched socks for five days, hiking around Switzerland to compare the new socks to the standard issue. The tests were described as "grueling" although I don't see how a six-kilometer (3.72 miles) hike is "grueling" unless it's straight up the side of an Alp. This news follows reports of the Israeli military developing a sock with two-week capabilities, which means there is now a Sock Gap between Israel and Switzerland.
