Darn Tough is a brand launched by Cabot Hosiery in 2004 and mainly produces outdoor sports socks. At the beginning of the brand's existence, 3,500 pairs of merino wool socks were given away at the marathon, allowing runners to test the durability of the socks for themselves, thus opening up the brand's popularity. Today, Darn Tough sells nearly 5 million pairs of socks a year and sells $40 million in sales, and has a large fan base in the field of outdoor sports. Its socks are all made in Vermont, USA, in addition to insisting on the use of the best craftsmanship, the complex and diverse climate and mountainous environment of the local socks are a natural testing ground for socks, which can be used for all kinds of skiing, hiking, and cycling experiments.
 
Darn Tough is positioned similarly to fellow American brand Smartwool, with a younger but up-and-comer look. Darn Tough is known as the world's most durable socks, promising a lifetime warranty, if the socks are worn out, they can be washed and sent back for a new pair, but they have not yet been sold in Chinese mainland, and the after-sales service is somewhat inconvenient. It not only produces wool socks, but also produces other chemical fiber blend-based socks, the current wool socks style is not as rich as Smartwool, socks function and detail design still need to be strengthened. However, the exterior design of the Darn Tough is more distinctive, changing the dark colors of traditional sports socks to a variety of bright colors and patterns, which is more attractive in appearance.
 
Darn Tough's wool socks are divided into running, mountaineering, skiing, daily and other series according to the use scenario, mainly due to the difference in the thickness of the sock body and the length of the sock tube. One of the most recommended is the Hiker series, which is designed for outdoor walking, and the Hiker Boot Sock Cushion also won the 2018 Editor's Choice Gold Award from Backpacker Magazine. Containing 64% merino wool and 33% nylon, the socks create a footpad structure that provides strong support for the foot by increasing the knit density in the middle of the sock sole to provide strong support for the foot, making it easier to walk and less likely to get tired. And because the composition of the fabric is reasonable, it can be worn in all seasons, it can be machine washed and dried at low temperatures, and it still has good elasticity after multiple washes. The price of each pair of socks in this series is about 160 yuan, but there is currently no purchase channel in China, so you can only buy it by yourself.
 
The Hiker Micro Crew Cushion is ideal for those who want to wear wool socks both for exercise and every day, this sock has the same cushioning design as the boot sock, although the sock is slightly shorter, the color options are more convenient and easy to match, the elastic sock body is more slippery than ordinary daily socks, and has the good breathability of sports socks. The model is also available in three sizes for about $150 per pair.
