The SportSupport leggings are knit as a heavier weight than our Everyday Leggings, with more design details built-into the legging. Both of our SportSupport leggings feature a 2-ply waistband that can be worn both pregnant or postpartum. The key differences between the Contour & Cuffed styles are the length & the knit design. Our Cuffed leggings were designed with a longer inseam, to be worn over your heels or tucked into boots. Our Contour leggings are for the mamas who prefer a shorter, ankle-length legging - whether you're working out or simply lounging!
