  • Brief liner is way too tight

    dethier - Nov 09, 2021

    The liner in these shorts is too small for the size of the shorts. I always wear large in running shorts. I have other Nike shorts from years ago in large, and the liner is just right in those. I've tried a couple of new Nike shorts and they all have the same problem: the liner is too small, making the shorts uncomfortable and restricting movement. Nike needs to fix this.

  • “Love the pink shorts, runner!”

    Wore the pink 4” shorts for the Minneapolis marathon and LOVED them. Perfect length for my liking, nice light material, and I received countless compliments on the pink shorts. Some made me laugh. Beware - only 1 pocket so not ideal for carrying multiple gels. My partner gave me my gels every 6 miles on the course but the shorts couldn’t carry them all at once.

  • Too small by far

    Although I used the website fit auto assistant and also double-checked the size charts the shorts are way too small for a M size
