    The best leggings!

    I've never really been one for leggings before, but as I'm starting to get into a more active lifestyle, I figured I'd try a pair from Knix. That was one of the best decisions I've ever made! I love that my leggings add a little compression and is leakproof, so I feel supported and secure. The fact that it has a deep pocket makes it even more of a 10/10!!

    Super disappointed, ordered these thinking they would be great for sports but I was pulling them up constantly.... super disappointing being how much I paid for them

    Sizing is incorrect.

    I ordered according to the size guide for my hips.

    I wore these leggings and I was constantly pulling them up. They wrinkled at the ankles.

    I would like to exchange for a different size if possible. Please let me know.
