I have a small waist but muscly thighs so what I find with many brands of leggings is that if they fit around the waist, they're too small on the legs. These Ron Hill leggings were just right and really good quality material. I tried them out this morning at my local Parkrun event and ran my fastest mile ever. I'm not saying that was down to the leggings, but they certainly didn't hinder my performance. Recommended.
