These were a lot thinner than I expected, & I'm a fan of thicker material so I had my doubts about them. A couple of sessions in and you start to realise why people love them. They're super comfy, VERY stretchy, and after a while you forget you're even wearing them. The only downside is the sound when you walk, which I guess is normal for this type of material. I'm not 100% converted, but I can appreciate them for what they are.
