The ultra-sustainable and environmentally friendly brand, Rockay, has done it again with the Rockay Agile socks. Like the best Coolmax socks, the Rockay Agile socks definitely deliver in all areas. They are breathable, comfortable, durable, and—best of all—when you buy any Rockay socks you will be doing your part to remove plastic from our littered oceans, so you know you are investing in a quality sock that you can wear guilt-free on each and every run!Read more
As we mentioned, the Rockay Agile socks help you save our oceans—one piece of plastic at a time—but how? Well, these socks are 100% sourced from recycled materials, more specifically, they are constructed from high-quality regenerated Nylon which is derived from unwanted plastic that has been removed from our oceans. The use of regenerated nylon, recycled elastane, and recycled Polyamide ensure these socks are comfortable, flexible, and breathable—the three most important components runners need to ensure their socks offer.
These socks are specifically designed to keep your feet cool and dry—no matter how far you run or how hot it is outside. As you can see from the pictures, these socks feature mesh zones in specially chosen areas to ensure that your feet are well ventilated. These are best for warmer weather or race days where no matter how cold it is, you know your feet will want to sweat as you pack on the miles.
By far the most comfortable socks on our list of reviews, the Rockay Agile socks are made for comfort. They feature a seamless toe design, which prevents unwanted rubbing, chafing, and hotspots—so you never have to worry about a blister again. They also provide exceptional arch support that you can count on even on your longest runs—so if you have a need for speed these are a great way to go. Their compression fit will ensure you have a comfortable and secure fit with the added bonus of pain prevention and a recovery time boost.
True to the Rockay brand, the Agile socks are incredibly durable and built to last. Although they are the lightest selection offered by Rockay, they are still made of high-quality recycled materials that will stand the test of time. First and foremost, they are odor resistant thanks to their Polygiene treatment—so you can wash them less often and extend their life. Their high density knitting also makes them much sturdier and more durable than the socks lower on our list. However, it is important to note, that to get the most out of these socks you need to care for them correctly. Make sure you wash these accordingly and hang them to dry if you want to receive all of the benefits they have to offer for as long as you can.
With their impending release just around the corner, you can already go ahead and pre-order the Rockay Agile socks, so you get them as soon as they hit the market. In terms of price, they cost the same as any quality running sock but have so much more to offer.

Good Daily wear
Not as durable as some liners
PowerSox Coolmax Socks are a crewcut design that offers reinforcement and softness. These are cool, flexible and have added support in the arches. They are a good all over, day to day wear with Coolmax technology running through every fiber.Read more
Outside of the Coolmax polyester, you have 38% Cotton, 16% Polyester, and 2% Spandex. With a blend like that, you get the wicking and cooling of the Coolmax, the softness of the cotton, and the stretchiness of just the right amount of spandex. PowerSox socks are also lined with the strike zone cushioning and toe reinforcements.
This is one of the reasons PowerSox made it on the 10 best Coolmax Socks line-up. With that Coolmax polyester blend added to more polyester, you get a super breathable sock with the softness of cotton. There isn't enough spandex to hold any heat in, it's just there to keep it fluid.
With that strike zone cushioning we mentioned, you get padding and breathability, which proves to be a great combination for comfort. These Coolmax socks can be used for a good run or a daily work sock -- that adds versatility into the design as well. They offer just enough support to help with activity but aren’t the sportiest in design, which makes them a bit more affordable and less flashy.
With their reinforced toe and the flexibility of the spandex, you get a solid design that doesn’t break down. Not even sweat build-up is an issue because it’s Coolmax. The wicking is always back up to the longevity of a design. Without all that extra moisture, your fibers stay strong and hold on longer than damp socks that collect microbes and bacteria.
These come in a pack and for what they are offering, are pretty darn cheap. You get support, reinforced seams, and all the Coolmax you need to keep you dry and comfortable at a fraction of the cost of some on the list. These are a great addition to your Coolmax daily wear.

Injinji designed these socks with a two-way stretch that is designed to conform comfortably to a woman’s foot. The narrower silhouette and two-way stretch provide some compression and support around the arch to allow for natural movement. The 5-toe design also keeps toes from rubbing, eliminating hot spots.

Criteria Used for Evaluation
Each sock features a varying percentage of Coolmax fibers as well as a few other key fibers. The most common are:
Nylon: Nylon is another synthetic fiber that is strong and versatile. It adds durability and softness to any fabric. When finely woven, it can be thin and soft, making it ideal for lightweight hiking liners. It can also take on some elastic and bulky properties that make it better suited for cold weather socks or boot socks.
Cotton: Cotton may seem counterintuitive in Coolmax socks due to its tendency to absorb moisture. However, this plant-based fabric can add softness to socks and can help fight odor better than many synthetic fabrics.
Polyester: Although Coolmax fibers are polyester, some companies add standard polyester fibers to their garments as well. Polyester has plastic-like properties that help repel moisture and keep feet dry.
Spandex/Lycra: Usually making up a very small percentage of the sock, this important component should not be discounted. A little bit of spandex offers elasticity to garments helping them retain their shape and provide some compression and support for the foot.
Coolmax socks can serve a variety of different functions and the materials used in their construction should reflect that. Features like smooth seams and a snug fit are essential for hiking liners. Whereas, arch support and cushioned soles are more important for running socks. We considered the key elements of each sock and how they should enhance your performance, no matter what you’re doing.
Whether you're choosing socks for warm weather or cold, having a pair that's breathable is always good. This may seem obvious for warm weather since you'll be sweating and want that moisture to move from next to your skin to the outside air where it can dry naturally. But why is having a breathable sock important in cold weather? Well, it's for the same reason and it's actually even more important. Even during winter activities your feet can heat up and start sweating. While this simply causes discomfort in the heat, when it's cold outside it can be downright dangerous. If you have sweaty, wet feet in cold temperatures this will almost instantly lead to your feet getting cold. This can cause a lack of feeling in your toes so you won't have as much control of your feet which can lead to falling and hurting yourself. In extreme cases, it can even lead to frostbite and hypothermia. In order to make sure you get socks that are breathable, look for products that are made from mostly synthetic fibers such as polyester. Synthetic fibers are literally incapable of absorbing moisture so it moves around them to the outside air where it can dry. Natural fibers such as cotton on the other hand love absorbing moisture so they get wet easily and stay that way for a long time.
Our feet and their 26 bones work hard for us, keeping us upright and allowing us to travel through our lives. In return the least that we can do is give them a home this is soft, comfortable, and cozy. By home, we mean your socks of course, and as with almost every piece of apparel, this factor is quite possibly the most important thing to consider. The products on our list have all been carefully selected because they have a good design, high-quality materials, and have been rated and reviewed as feeling good to wear. One thing to look for when it comes to this factor is options that have seamless toes. These tend to be expensive but can be absolutely worth it, especially for diabetics and/or those with circulation problems. Some of the products on our list do have seams at the toes, however, we were careful to choose ones that, if they do have toe seams, have ones that lie flat and don't cause the user discomfort. Another thing to look for is added cushioning in the heels and under the ball of the foot. Especially if you'll be wearing the socks while running just that little bit of added cushioning can make a big difference when you add it up over thousands of strides.
We've all experienced holes in our socks, especially in the heels and in the toes. These happen in these areas the fastest because this is where the highest amount of stress is placed on the sock during use. In order to help prevent this, you can look for products that have added material in these areas. We also recommend spending a little bit more for high-quality, brand name socks. It might seem silly to pay $10-25 for a pair of socks, but when you consider how much longer these will last you can easily see that they'll pay for themselves over time. What's more, is that you won't have to deal with the hassle of ordering a new pair or going to the store to buy them. While making this list we looked at the materials used in the socks as well as the construction techniques and then finally considered over 1600 user reviews to find options that are tough and long-lasting. Another thing you can do is to buy from brands such as Fox River and Darn Tough that have excellent replacement and return policies. If something happens to these socks and you're not satisfied you can return or exchange them for a new pair. This shows that the company is confident that their products are well made and long lasting.
As we briefly touched on above in the durability criteria, buying a high-quality pair of performance socks can definitely save you money in the long run. While at first blush it may seem silly to spend $10-20 or more on a single pair of socks, these options will serve you well for several reasons. First of all, they are much more likely to be made of high-quality materials that won't cause you hot spots, chafing, and blisters. An ounce of prevention beats a pound of cure any day of the week and twice on Sundays. Secondly, they will be more durable and long-lasting so you don't have to replace them as often as the cheap socks that can be bought in bulk. Finally, a lot of the options on this list come from companies that have excellent return and exchange policies. For example, if you buy a pair of Fox River socks and at any time are unsatisfied with them you can send them back to the company and they will send you a brand new pair. Not only does this give you peace of mind knowing that you'll be taken care of in case of a problem, but it also shows that the company is making an excellent product because they wouldn't be risking spending extra money by giving away new socks all the time if they weren't confident that their products would give the consumer a good experience.
Expert Interviews & Opinions
If you have sweaty feet or run or workout in hot environments, then the answer is yes, Coolmax socks are absolutely worth it. Using Coolmax socks will make a world of a difference and ensure you don't get any blisters due to chafing--try them out and you will see!
While Coolmax socks are really easy to wash and are really durable, you will want to make sure you wash them correctly and air dry them if you can. These socks are more expensive when compared to the average socks you can buy at any store, so make sure to take care of them, so you can get the most out of your purchase.
Other Factors to Consider
A good pair of socks can be functional in a variety of situations depending on how you use them. However, ignoring the intended purpose of your socks can lead to sore feet. For example, wearing thin hiking liners rather than padded hiking socks may be a bit harder on the bottoms of your feet. On the other hand, wearing thick boot socks for hot weather hiking will lead to overheating of your feet. Consider the activities and weather that you typically need high-performance socks for before deciding which will be best suited for your needs.
Type of Footwear
Moisture-wicking socks can do a lot to keep feet dry and reduce blisters. However, even the best socks in the world cannot prevent damage due to ill-fitting shoes. If you are experiencing persistent blisters, your shoes may be the culprit. REI experts recommend trying on hiking boots and running shoes at the end of the day when feet are most swollen to ensure an accurate and comfortable fit.
