I am used to wearing compression stockings from a medical supply store for venous insufficiency that are quite an ordeal to put on but these pants surprisingly weren't too bad even though I ordered a size down.
I used them for yoga and they seemed to help, definitely not as dizzy/lightheaded and felt my legs were capable of more than normal in terms of holding stances. I will have to see how they are when I use them again, they held odor pretty quickly for me personally so I had to wash them after one wear (albeit all day and for a workout) but I'm fairly used to that because I sweat a lot.
I like that there's some breathability in the fabric around the crotch and buttocks & they don't cling as much, however I'm not sure if that means it's not compressive there? In any case, I'll be purchasing more since they faired pretty well in comparison to the ones that were $140 from another online retailer.
I can't say they feel like the same compression as the medical stockings but for the price and convenience, I think these are worth it for days when I don't want to wear two layers of pants. Also, pockets! And soft...and definitely not see-thru.
