I bought about 6 pairs, roughly a year ago and they all fit the same way as the day i bought them. No, issues with them at all. I wear nothing else i wear them 12-17 hours a day maybe more when i'm working i'm a Commercial fisherman so sometimes i'll even work up to 32 hours straight and they are perfect the whole time. So all these other reviews are kinda BS. In fact i'm looking at buying about 4-6 more pairs to have a larger collection and color schemes. I only had issue with one pair, cause their is a area on the right thigh that itches like the fabric sticks out, but other than that wearable just like the rest, Amazing, i will buy more for sure... a must try. First time i tried them as i said i bought 6 pairs and never will go anywhere else.
