They seem to get a lot of attention. Some of the reviews compare them to a Lululemon pair they say is better, but these are definitely less $. I'm not a huge leggings wearer but wanted to try a pair for home and possibly casual errands or such. How do these fit at the waist? I'm wondering if high waist would feel like control top tights? I'm an apple and hate things compressing my stomach...actually gives me heartburn!
