The Definitive Crew Socks not only come with a fancy graphic, but also with Stance Infiknit™ technology with a lifetime guarantee. Infiknit™ technology With the new Infiknit™ fibre technology, Stance has developed a yarn that promises extreme durability combined with pleasant wearing comfort. The nylon used has a higher filament count. This gives the yarn a high density and thus a better tear resistance. Infiknit™ reinforces areas of greatest friction with greater durability, especially in the heel and toe area. Infiknit™ socks last at least 5x longer than standard socks.
