Lovely Annie Women's 4 Pairs Cute Cozy Knee High Cotton Socks HR158212 Size 6-9 …

What are these socks made of ? Some of us cannot wear polyester or wool. Need to know exactly what they're made of and the % of each.

Do these stay up with skinny calfs & narrow feet? (I'm a 7.5 shoe)

What is the fabric content????? I am allergic to wool......

Do the color flecks come across looking like lint/pills? The gray sock in the photo looks "pilly". Thanks
