In this Buyer’s Guide, we are going to focus on a number of factors you need to consider when buying wool socks.
Why ‘Merino Wool’?
It’s no secret that wool socks come with a heftier price tag than their cotton or polyester counterparts. However, the added benefits you’ll get with a better quality pair of wool socks is certainly worth the added cost.
Merino wool naturally wicks moisture away from your feet when you sweat. Dealing with sweat is a natural part of most outdoor activities, and having socks that pull moisture away from your feet means added comfort for long days on the trail. Merino wool also contains natural antibacterial properties. When combined, these two natural properties mean merino wool greatly decreases the odor of your socks.
Additionally, merino wool is capable of retaining more warmth when wet than other materials. It also won’t feel as sticky to the touch when wet. This means a lot when there’s a high likelihood of your socks getting wet when you’re tramping about. Bottom line: merino wool is the best material to keep your feet comfortable in almost any environmental situation imaginable.
As you know, there are many sock lengths to choose from. They range from no-show to ‘over-the-calf’ and ’knee-high’. Generally, over-the-calf and knee-high socks are primarily used for winter sports, in everyday boots, or as compression socks for distance runners.
Crew socks (also sometimes known as ‘midcalf’ or ‘midweight’) are excellent for everyday wear, especially during the winter months. Many hikers, however, swear by crew socks year-round, because of their extra ankle protection when wearing high-top hiking boots.
One-quarter, ankle, and no-show socks are primarily those that are used during the summer months or for workout purposes only. These socks are great to use with trail running shoes, but most hikers tend to shy away from them on long journeys.
Most of the best wool socks on the market today actually contain a blend of wool and certain other materials, as opposed to being 100% wool. This is largely due to the fact that merino wool, by itself, is actually weaker than cotton. This is only of the only drawbacks to merino wool, but by combining it with nylon, spandex, lycra, and a variety of other fabrics, sock manufacturers have produced more durable socks while still retaining all of the naturally beneficial properties of merino wool.
It’s important to know that a higher percentage of merino wool in a sock’s composition doesn’t necessarily reflect higher quality. In fact, some of the most durable wool socks on the market today actually contain a lower percentage of merino wool. In reducing that percentage, they are able to engineer a more durable sock. A higher percentage of merino wool, however, does generally signify a sock that will feel softer on your foot.
Wool socks usually come in a specific weight. This is usually advertised as ‘ultralight, light, medium, or heavy’. A heavier weight wool sock is generally better for use in colder weather or for heavy trekking. This is because they provide more cushioning than lightweight alternatives.
Lighter weight wool socks tend to be more breathable than their heavier counterparts, which makes them an ideal option for summer use or with insulated boots. The downside to a thinner, more breathable sock is that it will also contain minimal padding in comparison to heavier weights. Consider your desired activity when choosing between light and heavyweight wool socks.
Frequently Asked Questions
Did you know that wool socks can actually break down more quickly is machine washed in excessively hot water? This Frequently Asked Questions section will answer some of the most common concerns about wool socks so that you can use and care for yours to the best of your ability.
Will wool socks shrink when washed?
Wool can shrink when exposed to heat. When caring for your wool socks, you want to avoid washing in hot water or drying on a medium to high setting. Wash in cold water and dry on low. Better yet, hand wash or spot clean and then lay flat to dry. Hanging wet wool socks can actually distort their shape.
Can I use bleach or fabric softener with wool socks?
The short answer is no!! The chlorine in bleach actually destroys the merino wool fibers that make up most wool socks. Fabric softener should also be avoided because it can coat the merino wool fibers of your socks. In doing so, it will reduce their ability to naturally manage moisture and regulate your body temperature. In other words, they compromise your sock’s ability to function optimally.
Do I need liners for any of these socks?
The socks mentioned above are designed to be durable and perform optimally without the use of sock liners. In general, if you’re considering buying a wool sock with a very high percentage of merino wool in the fabric, it’s more likely you’ll want to purchase a liner. A liner, in this case, will simply decrease the wear on the sock itself and make it last longer.
There’s nothing quite like slipping into a fresh, comfortable pair of wool socks as you’re gearing up for an outdoor adventure.
