These socks have seamed toes, so they are not true diabetic socks -- the seam ridge can rub against the foot and cause injury to diabetic skin.  However, if you are looking for an inexpensive diabetic-style sock with cuff elastic that is not tight and yet will stay up, these are a good choice.

So far they have held up in the wash, keeping their shape and their color. These socks do run small, though -- women who wear shoe size 9 and up should probably order mens, and men who wear 11s or 12s will probably find the men's too small.
