Best exfoliator for legs?

I'd definitely say the Soap & glory flake away body scrub (http://www.boots.com/en/Soap-Glory-Flake-Away-trade-Body-Scrub-300ml_27894/) It's by far the best body scrub i've ever used, it's especially good for legs. It smells really good and after use your skin feels smooth, soft and moisturised. It's also not expensive and it's on 3 for 2! You can use your hands and you don't need so use very much, so it will last you quite a while.
