Whether you're dancing on your pedals, or to the '60s rock song bearing a similar sounding name, DeFeet's Woolie Boolie 4 inch Socks were designed to keep your feet warm, dry, and comfortable. As the name implies, DeFeet's Woolie Boolies were constructed using a blend of ultra fine New Zealand Merino wool, as well as Lycra and nylon. The Merino wool in the makeup helps the socks breathe, wick moisture, and resist the build up of odors, while also providing medium weight insulation for cool weather conditions. The Aireator mesh fabric on the forefoot and instep works to dump excess heat through its ultra breathable makeup, and the overall thickness of the socks' composition remains consistent throughout. This is something that sets the Woolie Boolies apart from many other Merino blended socks. In other words, there are no padded heels, toes, thin insteps, or other variances to cause friction or abrasion inside your shoes. Along these lines, deep heel pockets and smooth toe seams further prevent chafing. Rounding out the Woolie Boolies are four inch cuffs that provide a smooth wrap and ample coverage around your ankles and lower legs. The DeFeet Woolie Boolie 4 inch Socks are available in four sizes from Small to X Large and in the colors Black Sheepwhite, D Logocharcoal, and D Logogrey.
