Amazing for recovery
I thought these leggings would be great for running because of all the pockets (which are fantastic, and I wish them on all my running leggings!), but they didn't feel supportive at all during the run. I love running/walking with the the 2xu compression socks, so I guess I was expecting that level of support for my calves, and it threw me off that I didn't get that with the leggings.
Where they shone, however, was in the recovery afterward. I tried wearing them after a harder long run (including to bed), and had zero soreness the following day! Now these are my go-to leggings after runs.
I don't know if the MCS printing really does anything or if it's the graduated compression doing all the work, but these leggings are amazing for recovery.
