The seven inch tall cuffs on these Swiftwick Pursuit Seven Merino Wool Socks make a lot of sense. After all, you're likely to wear these thicker Merino socks when the temperature drops a bit and you opt to leave your thinner summer socks in the drawer. While they're certainly not winter socks, Swiftwick's Pursuit Merino Socks offer a touch more insulation which makes them fabulously suitable for trans-seasonal days that may start chilly and warm up as you tick off the mileage. The superior temperature/comfort range of wool ensures all day comfort. Swiftwick makes the Pursuit Merino Socks on a 200-needle knitting machine. The benefit is that you'll get a high density, seamless sock. The process allows variability in the finished knit of the socks, as different parts meet different performance requirements. For example, the cushioned footbed gives way to the thinner, channeled upper -- both components playing a crucial role to increase your comfort. When you slip into a pair of Pursuit Socks, you'll immediately feel that they're tailored for your feet. The Y-shaped heel contour assures no bunching or overstretched feeling in the back, and the front and back of the ankle have a half-density weave that allows foot flexion and extension without bunching or tugging along the cuff of your shoe. Compared to the Aspire socks, these Merino wool socks are thicker, but just so. You won't have a problem letting out the closures on your normal shoes a bit to accommodate the extra insulation. Thanks to the wide temperature/comfort range of wool, you can wear them on chilly days when your lightweight summer socks just won't do. If it warms up during the ride, no worries -- wool breathes better than synthetics and its hydrophilic nature will ensure that your feet stay dry and comfortable. And when we say that wool absorbs less stink than most synthetic fibers, it's true. The Swiftwick Pursuit Seven Merino Wool Socks are available in Black, Coal, and Heather Grey. They come in four sizes from Small to X-Large. The seven inch height makes them feel great in cooler weather. In addition, the taller cuff and multiple knitting patterns in the footbed and cuff add to the compression nature of the socks to promote blood flow in the feet and lower legs. And as you might guess, improved vascular performance means reduced fatigue and speedier recovery.
