These socks are very high quality. Silicone lining to avoid slip tabs on top and heal for easier donning and adjustment. Thick but not too thick. The downsides are that they are expensive and I feel like they are a little small. I ordered 8-12 M and I usually wear size 11.5/12 shoes. They fit a little but not to that extent but I would like them to be bigger or 1 bracket more sized for 12+. They stretch to fit, but I can say I'm in the top sizing category if that makes sense and is a little tiring.
