The product is called "super soft Madam Sheepwool Norwegian socks wool to Gr. 50", you should be able to go out at 2x sheep wool in the title that the socks are 100% or at least for the most part from sheep's wool. Unfortunately, this is wrong, they are 50% of polyamide, a plastic. Accordingly, the thermal insulation and the foot climate of genuine sheep wool socks can not be achieved, wet feet are the result. In addition, the yarn is very coarse and (compared with pure sheep's wool or cotton) hard, so you after wearing these socks in boots has the knitting pattern in the skin. These socks are to be worn in boots in my view totally inappropriate (it've tested), or at best as a bedroom or "TV socks" useful. After the fall 4750 even with shoe size 49 still plenty of (No, this is not self-evident).
