What To Look For
No matter your activity, it's important to choose a sock that fits the conditions in which you work out and complements your footwear, comfort and wear.
The thickness of a sock is a major consideration, both in terms of cushioning and insulation.
In hot, humid conditions, breathability is vital, so look for cool mesh panels and lighter fabrics that are able to wick moisture away from your foot. Wicking (provided by fibers such as Merino wool and bamboo) keeps feet dry, providing comfort and protection from blisters. In addition, seamless construction reduces irritation.
Common Pitfalls
Beginning runners and those who have stuck with one brand for a long time may believe that socks are not that important, but not all socks are created equal. Try a number of brands and styles, and avoid those that cause your foot to slide around inside your shoes. Always try on socks with the shoes you intend to exercise in to get real results.
Where To Buy
You can find running socks through large sporting goods retail stores if you want to try the fit in person and compare brands side by side. Most major chains offer a number of choices and can special items on request.
If you're more interested in saving money, consider shopping online. Many brands sell directly through their website, such as WrightSock (wrightsock.com) and Darn Tough (darntough.com).
Cost
The cost can vary greatly, with a pair of socks priced between $5 and $15 depending on the brand and construction. If shopping online, it may be possible to find a seller who offers free shipping. Ask about the return policy (and any service charge or restocking fee for returns) if you are buying from an online seller, particularly if you are buying a brand or line for the first time.
Comparison Shopping
Consider special features you may require based on your running style and peculiarities, such as lateral cushioning or anatomical design, which offers individual left- and rightfoot socks. There are also styles made with articulated arch bands (elastic or Lycra in the arch) to help keep the sock properly fitted on the foot, as well as those with a Y-shaped heel gore to prevent slipping.
