These seem like an awesome idea! However, when i put them on, they are the perfect combination of clingy and slippery to pull themselves down while I'm wearing them. If I'm standing still, they feel like the right size; it's just that when you walk, or stand up and sit down, the stretchy part stretches in perfect harmony with the slippy part slipping so they would literally end up around my ankles if I didn't keep pulling them up. I don't know if I got a bad pair or what, but nothing I did fixed them! :(
