These are amazing. Loose and comfy, not too short/too long, and the best feature is they have two decent sized zip pockets. Perfect for running/sports without needing a bag for phone & keys. Wish I could find these in more colours!

I have several Nike running shorts which are a great fit but tried these Adidas for a change. They are a good length, slightly longer than Nike, and have a drawstring wait and small internal pocket. They are a very generous fit, I bought the medium (same as I buy Nike as I'm a size 10-12) but these were a lot bigger, good job there is a drawstring waist.Happy with my purchase though :)
Wanted an additional pair of running shorts for holiday to go along with my old faithful Adidas Marathon 10s and these are the perfect updated version. Really lightweight material, perfect sizing and a great price.
Bought this about a month ago and I have absolutely no regrets! My favourite pair of workout shorts and the fit is great.
I have narrow hips and the size and fit were as expected for me. However, the additional inner layer of fabric is faaaar from seemless and shows underneath the top layer no matter what I do. Had to send it back because of that
Bought for playing football in, not too short or too long, love that they have drawstring to tighten.
Hard to fault anything Adidas, it's usually all great quality. I took a star off as I didn't realise these shorts had the built in mesh net underwear part. I don't like that normally so wouldn't have gotten them if it was noted in the ad. This is more a star off for Asos than for the shorts though. Haven't run in them yet as it's still Winter in Melbourne but I'm sure they'll do the job
its comfortable and definitely easy to work out in, as well as just using it as lounge wear. only complaint is that it has an underwear like seaming in it, not sure how to explain it, but it's a little uncomfortable, for me at least. seems easy enough to remove without causing damage though.
