As a relatively short woman (5'2") I find it extremely hard to find reliable leggings for training and usually have to default to shorts because either they are too long, too loose, or both. Most training leggings don't stay up and are generally more annoying than anything, particularly for HIIT, weights, etc when you're going to be doing a lot of leg movement. THESE are different. I really appreciate the 7/8 lengths because they are basically full length for me (teehee), and these are particularly flattering. The panel makes them more interesting than just black leggings, and make me feel like an "athlete", particularly with the mesh details that render them so much more breathable. I find that I can easily get through a HITT workout where I'll be sweating and moving every which way without even having to think about them (which is the point!).
I appreciate the high waist (helps them stay up) and the rather wide 'nike pro' band which makes them feel extra snug. The actual material is extremely sweat-wicking and squat-proof (in black, at least).
