That they are not as they appear in photos.
The photos do not show that there is a section for the big toe and the rest is open. The photo shows as if the whole toe section is one opening instead of two.
They work for what I want but just not what I thought they would be.

Not as pictured
The pictures make it seem like these are open all the way across. There are actually two holes. It is quite tight on the big toe. I will keep these, however I would not order these again.

Comfortable toeless socks
Very soft and comfortable. However, the elastic is too tight. Should be wider so circulation is not cut and you are able to wear it at night. Therefore, is not good for diabetic and heavier people. Larger sizes should be available.

Terrible Quality, fell apart
Very poor quality. Came apart after one washing. Unraveled. Would not purchase again. Wish I had not purchases the first time.
