Looking to complete the look of your Seirus apparel? Then you need to get the Seirus Stormsock Fleece Lined sock. This sock brings everything you need, whether you"re an athlete about to head out onto the court; or if you"re going to be trekking through the snow for some time. The exterior of the sock is made from a stretch nylon fabric that truly will stretch and move with your foot no matter where it moves. However, the sock itself is super thin and so, as it stretches and moves, it"s also not going to get in your way at any time. It"s the fact that it"s so thin that allows this sock to easily fit into any footwear - whether it"s a bulky ski boot, or a slinky flat. Inside, you get more of the same great quality features that you find on the outside. In here is where the fleece lining lies, which not only helps to keep the foot warm, but also helps to wick moisture away from the foot, keeping it clean and healthy, too.
