The Darn Tough Coolmax Vertex Ultra-light is one of our favorites for its fantastical comfort and overall durability. Sporting a specific fit, it compresses and adds a little bit of padding in all the right places. It doesn't move on the run, nor does it change shape. The combination of Coolmax Polyester, nylon, and Lycra feels dreamy against the skin and stretches for a perfect fit, while the truly no-show toe seam ensures that there are no bumps or creases to rub or itch. If you want a comfortable and lightweight sock, this is a super durable and high-value option. Darn Tough also offers an unconditional lifetime guarantee that backs its products 100% throughout its lifetime.

Our Analysis and Test Results
The Darn Tough Ultra Light offers a lightweight, yet super durable construction that will have you logging many miles in the years to come.
This sock offers awesome comfort in its architecture. Indeed, this is a sock that we couldn't stop grabbing out of the drawer, no matter what we intended to do. We found ourselves wearing it around the house just as much as in our running shoes. We love how it stretches in order to easily slide over our foot, but once on simply hugs and supports rather than constricts. There was not a hint of tightness or pinching anywhere, and the no-show seam technology used in the toes will make you forget that there is even a seam there at all.
This was an especially awesome feature, as often times the toe seam can rub and start blisters on long distance runs, depending on how it sits on your feet and in the shoes. We never found this sock to be either too hot or too cold when out running, and couldn't even think of anything to complain about simply for the sake of it. It is marketed as being ultra-light in terms of thickness, but it does have consistent cushioning underfoot. As a result, this is best for those who love ultra-lightweight construction with a little bit of support.
Size is true to fit. The sock does a great job at compressing around the arch with a thick band of elastic and around the collar. We appreciate the small tab that offers a little more protection against the Achilles as well, although it is not padded. In general, we appreciate the fit and like that it doesn't bunch or roll while on the run.
Wicking & Breathability
This sock is lightweight and does a great job at wicking moisture with excellent breathability. It has plentiful surface area for venting and evaporating moisture. While running on hotter days, we noticed that the moisture readily moved from the foot to the outside of the fabric. While this sock does not dry quickly, it still provides the performance required for longer adventures on either the road or trail. Overall, a great option for warm to cold temperatures.
When it comes to slip prevention, this sock is a little below average. It provides less slippage than other lightweight contenders because the material grabs the shoe. Overall, this sock scores a little lower than thicker options but does pretty well for its lightweight construction.
We love the durability of this sock. Despite its thinner design, the threads still look like new and haven't been compacted or totally worn after 30+ miles of travel. Not only that but like all Darn Tough socks, it comes with an unconditional lifetime guarantee. This simply adds to the value…especially since the product lives up to its claims in our testing period.
This sock is a little expensive upfront but comes with an unbeatable warranty. It's very durable, and since it was one of our absolute favorites, and think it presents a great value. Its unconditional lifetime guarantee also can't be beat…adding value in the long run.
The Darn Tough Coolmax Vertex Tab No Show Ultra-light is a sock we are happy to recommend to our friends and our readers.
