Good for wearing with Vibram Fivefinger shoes
Size: 8-10, Color: Black 5 Pairs
They are good, comfy socks that fit well on a size 43 eu (9.5-10 US) foot in medium.
Be aware that these are the same socks that you get when you order Caidenieu toe socks and dozens of other listings as well. So just buy the cheapest ones you can get. They come in the same bag with the same cards and everything. I wear them with my vibram fivefinger shoes very comfortably.

Great socks but overly snug
Size: 13-15, Color: Black 5 Pairs
Socks fit great. Very comfortable. The elastic around the ankles gets tight and uncomfortable as the day goes on though. Durable after many washes and they do not shrink. Colors don’t fade. They keep the toes warm and separated, which provides some bunion pain relief.

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.
