The Darn Tough Style 2009 Men’s William Jarvis Boot Sock is a mid-calf merino wool boot sock knit with full cushion density throughout the foot. The dense cushion absorbs impact on hard job sites and long trail miles, and the merino-heavy blend handles temperature regulation across seasons without the odor buildup that comes from synthetics. True Seamless toe construction removes the toe-box seam that causes blisters under load.
The Timber colorway a rich brown that reads like worn leather. Mid-calf height clears the top of a standard work or hiking boot, and the merino wool blend wicks sweat and dries faster than cotton through consecutive wears. The cushion structure is what separates this style from lightweight socks — real impact absorption for guys who put real miles on their boots.
Darn Tough is family-owned and knits every pair at their mill in Northfield, Vermont. Lifetime guarantee is unconditional — wear them out, get a new pair.
