One of the most comfortable socks I have tried...correct sizes and elasticity. Also, they are slightly more transparent than the others, so you can more easily wear tights without them being too visible...the downside is that the elastic at the thigh stretches quickly, resulting in them slipping down

I bought them for my mother. They stay in place. On the label on the socks for washing instructions, 35C looks like 95C.
I think it is very important for a compression sock to cover the knee, especially if there is pain behind the knee. Pain behind the knee is quite common in people with venous insufficiency and is responsible for problems in walking. There, the lesser saphenous vein connects with the deep vein through a perforating vein (which pierces the superficial layer of the peritoneum). Usually, in the area behind the knee where the connection with the deep vein occurs, the first valves in the superficial veins start to deteriorate due to blood pressure, and then they deteriorate lower down (we have valves every 5-10 cm in the veins of the calf), leading to the formation of varicose veins.

After the total hip arthroplasty, they put on my wife (in an expensive private hospital) a pair of tight Rizomirio anti-thrombotic stockings, with the XL indication, and a no-name brand !!!.
I searched for it, found it at POH Medical (thank goodness for those people), took measurements and ordered a pair of Medivene Thrombexin 18. 1. The product does its job well and provides relief. 2. It remains in its size without overflowing! 3. It is a well-known and Made in Germany brand). I highly recommend it.
