I bought socks from the same series five years ago, but they got holes in the front near the toes over time. So, I decided to buy socks from the same company again, but this time with open toes and above the knee because I had knee pain that was bothering me at work. I looked for reviews and only saw one negative comment with one star. Despite that, I bought them about 20 days ago and I am very satisfied. They are exactly what I wanted. Their material is very high quality and durable. The silicone edges are very stable and hold firmly. It is very important to choose the right size. Measure your foot carefully according to the instructions. Also, I only wash the socks by hand. An important tip that I read somewhere: wear graduated compression socks when your feet are completely rested (like in the morning) and not when they are already swollen. If you have to wear them in the afternoon, first elevate your legs at about a 45-degree angle (against the wall) for 10 minutes, giving a gentle massage IN ONE DIRECTION (!) from the ankle to the knee.
Tip: You could turn the socks inside out if the silicone bothers you, like I did. They still hold firmly and don't fall down.
