Thru-hiking the PCT is not for the faint of heart. Though you might go it alone, you'll always be in good company with a pair of great-fitting, moisture-wicking socks. Your best bud is a lightweight hiker with enough cushion to keep your feet in prime condition. If you make it to Canada, swash those socks immediately and start planning the next trip - there's always available mileage when your socks are unconditionally guaranteed for life.
