I'm an older runner and recovering from a long lay off with a hamstring injury so need all the help I can get.
These shorts provide really good compression even on my slim legs. I'm 5' 11'' and weigh 11 stone 2lbs, so quite a slight build. I bought a medium and they're perfect.
One of the best features is the length. I have 2 other makes of compression shorts and both sit mid thigh. The Core Compression Shorts are longer making me feel like my whole thigh is supported which is exactly what I want.
I'm considering buying another pair to replace my other ones in rotation and might also look at a pair of Light Speed for even more compression.
I'm a big fan of all my 2XU gear and it's rapidly becoming my favourite brand. I now have the compression shorts, compression socks, ordinary running 7'' shorts and a running cap, so building a good selection.
