    Perfect workout shorts

    These might be the best pair of shorts I have ever owned. Doesnt feel like your wearing anything, so comfortable, leak proof and do not move when your working out. I didnt have to adjust these once! Please make more colors.

    Uncomfortable waist

    Mid rise waist is built with an extra tight band just at the very top of the waist band. It digs in, is uncomfortable and creates an unflattering lump.

    If the waist band was the same material and fit throughout they would be great shorts.

    Who knew Knix made amazing active wear

    I just purchased 2 complete outfits from knix to workout with in 2026! I absolutely love each and every piece. From these great shorts to the pursuit jacket the quality and fit are beyond my expectations at a reasonable price point! Thank you knix.

    Great idea but

    Super important that the inner short shouldn't ride up and it is much more comfortable and flattering with a high waist. This sits at a waist level where it just emphasizes a muffin top even if you don't have one.

    Cute but ride up

    I'm an avid runner and was super excited to get these leak proof shorts. They are super cute but ride up when running and I'm constantly having to pull them down. They might be ok for doing weights but was really looking forward to using them for running.
