Size 8 - 15
Size: 10-12, Color: Black 5 Pairs
These socks were so well reviewed that I didn't quite believe my boyfriend when he said they wouldn't fit his size 11 feet.
So I went and tried them on my own women's size 7 feet and yeah, no. Maybe the arch & heel part could stretch to accommodate his feet (but it would be stretched quite thin) but the toe part is already very snug on my short little toes, there's absolutely no way they'd fit his gangly toes.
So I looked at the package to make sure we hadn't been sent the wrong size, only to see "size 8 - 15" on the barcode. So it turns out it doesn't matter what size you pick, this is a one size fits all situation, and that size does not fit the long toes of a tall man's size 11 feet

Quality not as expected
Size: 10-12, Color: Black 5 Pairs
Upon opening the socks looked all right they fit well, but I questioned the durability. Unfortunately, within a few weeks, the stitching started to separate and now their are holes in most of the socks rendering them useless.

made well
Size: 8-10, Color: Black 4 Pairs
These socks fit really well. Comfortable and the price is a breath of fresh air with other brands of toe socks getting crazy expensive. Just went for my evening run and they felt GREAT.

Comfy and Warm
Size: Women 6.5-7.5, Color: Raisin
I'm very happy with these Original Slipper Socks. I normally wear a 6 1/2, so got these in XS/6 1/2-7 1/2. They are a little long on my feet, but they'll do. I'd rather have them be a little long than a little short, and perfectly sized slippers seem almost impossible to find these days. These slipper socks have a nice, comfy wide toe box, and the cushioned sole is soft, warm, and comfy. The suede on the bottom of the sole make these quiet and very comfy to wear around the house. The wool sock uppers are not itchy, but as comfy as a pair of warm socks.
