These socks are made of a cotton & polyester blend giving it a silky feeling. I slide across my hardwood floors easier than with regular cotton! My calves are athletically thick and the major stretch in these is the top band. It’s a little shorter than regular crew socks coming up to just below my calf muscle (size 7.5 women’s). The colors make it a beautiful addition to my work wardrobe! I experience redness from the top band after 24 hours of use. If you remove them earlier or have a thinner calf then you should experience no issues. They are actually less tight than normal crew socks I typically buy. I have already purchased many more from this brand!!UPDATE: April 2022Received my new socks and they are just as silky and comfortable! The graphic is super cute & I added a new picture.
