I'm going to write this review it two parts. I will come back and update in a couple days. Because your hair darkens after using it.

I have read a few bad reviews and as a result was not going for much, however I am pleasantly surprised.

I like the crew & mini crew socks so much that I thought these would be great under my work shoes, & they are, they make my shoes/feet much more comfortable, no more blisters or smushed toes! However I do find the compression maybe a little tight on my calves by the end of the workday, it depends how long or hard of a day it's been! Also they are not quite thin enough for my work shoes, they bunch up a little at the top of the foot in my "mary jane" style shoes, although I don't feel anything, it doesn't make them uncomfortable, but if you're looking you can see that but I still wear them anyway (the pants cover that part)! When the weather is cooler, they'll be perfect under boots (I'm referring to regular "fashion boots, not snow boots, lol) For running, maybe they're slightly too thin, or maybe it's just that they're not cotton so don't grip as well, but I feel my foot slide a bit in my sneakers. If I was going to use these with a pair of sneakers exclusively, then I'd buy a smaller sneaker size to fix this, but I think I prefer to wear their micro crew toe socks for running/walking & keep these for work or after run recovery.

UGH. Was going to order chalk, but saw this and wanted to avoid chalk residue. This stuff left a film on my sons hands and did not help with grip when film was rubbed off. The liquid is messy to use. Turned out to be a complete waste. I don't recommend.
