The socks have a small tight elastic band at the top.  I have to roll the sock down so the band is on the smallest part of my ankle, and even then it's tight.  You can see the band in the photo.  I cut the band off one pair of socks, and it was a big improvement, if the fabric doesn't unravel.  This seems faintly ridiculous to me.

The socks are too long to fit the size range indicated.  My feet should fall in the middle of the range, and the socks are loose at the toes.  If you have long thin feet, this might be good for you.  NB: the sock size is not the shoe size.

Finally, the fabric blend is not that indicated in the Amazon description -- for example, the package says 20% polyester and 5% spandex.  This doesn't bother me other than as it indicates careless marketing.

Close, but not quite a great banana.
