Overall Fit
The Darn Tough Coolmax hiker boot sock is available in medium, large, and extra-large sizes. It’s been found to be true to size in the majority of cases, and there has been little indication of abnormal stretching. And although we would like to have seen smaller sizes included, overall, the fit was superb.

Breathability
Since they are made with Coolmax material, these socks have good breathability. They easily help to keep your feet relatively cool and comfortable, no matter the terrain.

As expected, perspiration doesn’t really stay next to your skin very long at all. The combination of good materials and quality workmanship makes these socks one of the best for keeping your feet cool and comfortable.

Durability
Darn Tough, as their brand name implies, is known not only for their wide array of selection but also for their overall toughness. These socks feature tightly woven material that is mid-weight and quality seams. It’s little wonder why they are more than willing to offer a lifetime warranty.

Comfort
In the arena of comfort, these Coolmax socks from Darn Tough really show their merit. Not only is sweat wicked away from your skin quickly, but the thicker cushioning also makes each step feel lighter and more comfortable than the last. Also, the sock is designed to stay put- so there shouldn’t be any worries about slouching socks getting in your way.

Summary
If you’re looking for a new pair of hiking socks for your hiking boots that are designed to go the distance, this pair from Darn Tough should be at the top of your list. Designed with the avid hiker in mind, they have proven themselves to be tough, yet extremely comfortable.

Overall Fit
These liner socks from Injinji come in a good range of sizes, from small to extra-large. They also easily conform to your feet and remain true to size throughout most of their lifespan. Their anatomical fit and five-toe design make them easily one of the most exacting socks when it comes to fit on the market right now.

Breathability
Constructed from a lightweight Xtra-life Coolmax fabric, these socks excel at keeping your feet cool and dry. In addition, they easily allow air to circulate around your feet and toes without too much hindrance.

Keeping perspiration off your feet and you comfortable is one of the areas where these socks really excel. The lightweight material and overall design make it easy for you to keep the temperature of your feet comfortable and the sweat from making a nuisance of it.

Durability
While the lightweight material is a great thing to help keep feet relatively dry and comfortable, the liner socks are not designed to be worn alone, and their overall durability is somewhat lacking. While they are certainly well constructed, we would not suggest wearing them without another pair of socks to protect them from rips and tears.

Comfort
Some hikers and outdoor enthusiasts may be put off a little bit by the five-toe design of these Coolmax socks, but we strongly suggest you give them a try. Once you find the right fit for your feet, you’ll be comfortable enough to wear them everywhere you go.

Summary
If you’re looking for a liner sock that has the comfort of Coolmax material and superior design, the Injinji socks are a top choice. Anatomically designed for comfort, control, and to prevent many food-related issues, these socks should definitely be in your hiking apparel.

Overall Fit
This option is designed to fit a wide range of people with a single, stretchable size that tends to run a bit large. And while it works quite well for most people, those who have smaller than average feet may want to consider other options.

Breathability
They are made from a unique blend of Coolmax material and other fabrics to create a liner sock that is not only easy to wear but also fantastic at allowing air to circulate around your feet. They work very well in hot weather, helping to keep your feet cool and dry, and are certainly an asset while hiking during the colder months of the year as well.

Whether you’re out and about in cooler temperatures, or sweltering heat, your feet are going to sweat. That sweat can contribute to painful blisters, so most hikers chose to wear some type of sock to pull the moisture away. This particular pair from Bridgedale helps to do that splendidly.

Durability
While not as durable as some of the more robust Coolmax socks on this list, these liner socks from Bridgedale can certainly go the distance. While we wouldn’t suggest using them as your only socks for prolong periods of time, these will last for a good while with proper use.

Comfort
These socks won’t win any awards for looks. They just might, however, win one for comfort. Despite the lack of serious cushioning, the overall design and fabric used to make these Coolmax socks some of the most comfortable we’ve found.

Summary
They may not be the most fashionable choice on this list, but the Coolmax Liner socks from Bridgedale may just be the most functional. Designed to keep your feet dry, comfortable and ready to face the next hike, this is a one-liner sock you’ll probably want to keep around.

Overall Fit
These socks range in size from small to extra-large and are usually true to size. In addition, the crew length of the sock makes it a good choice for those who like to wear higher hiking boots or shoes.

Breathability
While this pair will certainly keep your feet comfortable overall, they don’t offer as much breathability as some of the other choices on this list.

Like the other examples of Coolmax socks on this list, these are designed to pull perspiration and moisture away from your feet to help keep you dry and comfortable. These socks also dry relatively quickly, so keeping your sweat from affecting your enjoyment of the great outdoors is easy.

Durability
This option is made from partially recycled materials, and is surprisingly durable, proving that not all recycled materials are of a lower quality or standard. In addition, the seamless toe closure and padded heel and toe allow for added toughness in tear-prone areas.

Comfort
The combination of Coolmax material and stretch nylon and spandex allows for a great overall fit, as well as a great deal of individualized comfort. The mid-weight fabric is also a great choice for hiking in cooler weather, and the cushioning in strategic places only adds to the overall comfort levels.

Summary
The Thorlos mid-weight hiking crew socks are a great choice for those times when hiking in comfort during the cooler winter months is the name of the game. The padded heel and toe, durable seams, strategic cushioning, and overall fit combine to make this one of the more comfortable crew socks on the market.

Overall Fit
These socks fit easily into most low athletic shoes. They offer additional arch support, so there is some compression. Additionally, they have a cushioned sole, giving these athletic socks an overall comfortable fit.

Breathability
These socks are relatively lightweight. The breathability of the material is top-notch, as it is made of moisture-wicking 40.6% Coolmax, 57% polyester, as well as 2.4% of Spandex. This cocktail of cooling fabrics offers great breathability in any sport where you'd expect to feel some heat.

Overall they are very good at pulling sweat and perspiration away from the feet. It should be noted, however, that unless your shoes allow for the moisture to escape, there is little chance of the moisture doing so.

Durability
While these socks get high marks for comfort and breathability, these socks leave a bit to be desired when it comes to durability. Some users have claimed the socks "ball up" after only a couple of washes.

Comfort
They easily conform to nearly anyone’s feet and sit so comfortably in your shoe that you’ll barely even know that they’re on your feet. The added cushioning, arch support, and heel tab keep your socks comfortably in place. That way, less time finicking with your socks and more time playing the supports you love.

Summary
If you’re looking for a pair of great Coolmax socks that are perfect for running around in hot weather or while wearing low profile shoes, these socks are hard to beat. They’re comfortable, adjust to your feet well, and most importantly, allow your feet to breathe during intense exertion.

Overall Fit
The majority of customers found these socks to be well-fitting, if slightly loose around the lower calf area. The inclusion of Lycra within the sock makes it relatively easy for them to stretch into the shape needed but within limits.

Breathability
These socks do allow your feet to breathe adequately, but they are not as well ventilated as some of the others on this list. This is likely because they are on the thinner side, with less material to wick away moisture. For most purposes, however, including regular outdoor activity, they serve quite well.

Durability
These socks are created with a combination of nylon material, Coolmax material, and Lycra, which makes the socks fairly durable and keeps the socks in place. One complaint that we observed was that the socks were found to be remarkably thin.

Comfort
Although these Lorpen socks offer comfort in the toes, they do not have cushioning, as they are meant to be used as both a sock and liner. It is not surprising there were a few complaints about the thinness of the socks being an overall comfort problem, but they were few and far between.

Summary
We certainly would have liked to see a thicker layer from the Lorpen. However, their other features make up for any issues with thinness. Overall, they are a good general-purpose choice for socks that feature the Coolmax material.

Overall Fit
The majority of people found these socks to be a snug fit overall, and easy to keep on their feet, no matter how intense the activity they enjoyed was. There were a few instances of the socks being a little too small for comfort, so it may be worthwhile to consider ordering a size up if desired. The socks themselves come in sizes ranging between small and extra-large.

Breathability
When it comes to breathability, these socks are certainly a contender for one of the best. The combination of polyester, nylon, Coolmax material and spandex allows for a significant amount of air passage in and around the foot, especially around the bottom. While some found the socks to be a little too thick to allow for the amount of circulation they wanted, most found the balance between thickness and breathability to be just about perfect.

The majority of the material that makes up these socks is Coolmax fabric, so perspiration control isn’t too much of a problem.

Durability
These socks feature both a reinforced heel and toe area, which help to prevent holes and frays in these two common problem spots. In addition, the use of a small amount of nylon material and spandex within the sock allows for additional strength and flexibility overall. These factors lend themselves to increased life for the socks in a wide range of uses.

Comfort
One of the nice features of this particular pair of socks from New Balance is the use of a stability fit design for added arch support. Often, low-rise athletic shoes will need a bit of help in the stability and support departments, so having a sock that helps can make a huge difference in the comfort level overall.

In addition, the socks are designed specifically for either the left or right foot and provide an anatomically correct fit for added comfort.

Summary
If you’re a runner or an athlete that likes to truly move in comfort, having a good pair of socks can make all the difference. While the size of these socks may run a bit small, overall they are a great choice for those who need a great balance between comfort and perspiration control.

Overall Fit
Oddly enough, these socks are currently only offered in a size Large. A large will fit shoe sizes 9 - 12.5 (men's). They have a nice foot feel thanks to the midfoot spandex and seamless toes.

Breathability
Thanks to the Coolmax fabric in these socks, there is a great amount of breathability. They are specifically designed to provide airflow around the foot, proving a comfortable environment for your feet. The weave of the fabrics is specially designed for faster heat dissipation.

These socks absorb moisture and sweat quickly. Users have commented that they take longer than usual to dry when washing, but there haven’t been any complaints about them feeling wet in the shoes. An added bonus to Coolmax technology is that it also gives the socks a decent amount of odor resistance.

Durability
Solax has added reinforcements into the areas of these socks that are typically the weakest. They are reinforced with durable fibers in the heel and toe. There are three pairs included in each pack and you can expect them to last for quite a while.

Comfort
These socks are very comfortable and feature a cushioned sole that aids in shock absorption when running or exercising. Additionally, there is also extra padding in the Achilles area. The spandex arch support also provides a nice tight feel throughout the foot. The toe area is seamless which prevents against chafing and blisters.

Summary
These are a great versatile pair of socks that are comfortable and will help to keep your feet from overheating. They are available in multiple styles and a few colors. We would have liked to see more sizing options, but hopefully, that’s coming in the future.
