This is a cotton sock. The yarns of the knit are gassed in the spinning mill. During this process, a gas flame burns off all the fluffy fibres. This gives the final sock a slightly more luxurious look than an average sock. State-of-the-art knitting machines are used for the knitting process. While an average sock is commonly produced in a faraway place on simple knitting machines with 160 needles, this sock is knitted with 200 needles. The result is a high-quality luxury sock. Each sock is adorned with a small logo under the hem, featuring the letter "F". The socks have flat toe seams and a non-binding top. This means that there are no noticeable seams around the toes and that the cuff doesn't pinch the calf.
