Hmm, are they jeans or leggings? I can't decide. They're too thick to be leggings and too thin to be jeans. All I know is that I've worn them almost every day for a week and I'm not going to stop anytime soon. From the founders of L.E.I., SOLD Design Lab's super-stretchy, pull-on skinny jeans (the "Spanx of jeans," I've been told) are quite possibly the most comfortable piece of skin-tight denim I've ever worn.
