Lindsay S.wrote a review of CW-X 3/4-Length Stabilyx Tight - Women's on August 10, 2017
Familiarity: I've used it several times
I often have trouble with runner's knee in my right knee when I push my mileage above 4 or so miles. I've been using k-tape for the last few weeks which has really helped, but I hate throwing it away every week and having to reapply, so I thought I'd try these tights. First off, the compression is not as extreme as I was expecting - I actually feel like lululemon's Tight Stuff Tights feel tighter overall. That being said, I wore them on a 5.5 mile run today and I did not feel any pain in my knee, so they definitely help to stabilize my hip flexors and knees. I also maxed out on my deadlifts 2 days ago, and the compression did seem to mitigate any hamstring tightness/pain I was feeling from lifting. I did feel like the fabric was bunching weird behind my knees though, and it was causing some uncomfortable pressure in those areas which I did not like. They also do not breathe very well, so they were pretty warm. I wore them at 6am on a summer morning, but definitely would not wear them on a summer afternoon. They are probably more suited for cooler spring/fall runs. (And this is coming from someone who gets goosebumps when its 70 degrees out).
I am around 5'2'' and 125 pounds, with a fair amount of muscle. I have a 26" waist and narrow 35" hips. The size chart put me between sizes but I went with the XS and happy I did, the S would not have provided adequate compression. I'm not sure why everyone thinks these are the tightest pants ever - yes, they're tight because they are compression pants, but it wasn't a struggle to get them on at all. And I actually needed the drawstring in the waist to keep them from sliding down while running. I do wish that these were high-waisted - the low/mid waist combined with a tight compression fabric will 100% give you muffin top, no matter how lean you are.
