These are fine socks. Nothing fancy. They are pretty thin cotton, so I wouldn't recommend them for heavy workouts or anything but they are comfortable to wear casually. The ankle elastic is comfortable--not too tight, but not loose and falling down. I got the 4-10 size and wear a 9 and it's comfortable but the ankle elastic is dipping a bit in the back, so I'm not positive it would work for a size 10 foot. But you can't beat the price of this 10 packs that's for sure--99 cents per pair!
