Leg part is TIGHT
Size: X-Large, Color: Black
I am a size 15, and the foot portion is comfortable enough, but the fit of the leg portion is so exceedingly tight that I can't wear them for long, which makes them worthless. I would return them if I didn't already toss the packaging.

I wear a women’s size 9.5 and I got a size Medium. They fit perfect, they aren’t super heavy, but have cushion where needed. Perfect for my steel toe boots

Quality and durable socks
Size: Large, Color: White (6-pairs), Number of Items: 6
Great quality socks. This pack was a lot taller on the cuff and bigger than previous batches I have had. Not sure what the change was, but giving it 4 instead of 5 because I preferred the smaller shorter ones they previously made. But these are great quality socks, and last a long time.
