Very frustrated. Opened upon receiving so that it can expand. It’s been 6 hours and still hard as a rock and curled up. Wondering how long it’s going to take to expand to isn’t normal shape.

negative


Ex Input:
The socks while feeling comfortable when wearing, left the deepest and longest lasting mark on my legs of any socks I have ever worn. I am a woman who wears a narrow size 11 shoe. I buy men's socks because they're easy to find rather than a specialty size woman's sock. I am surprised they are men's socks and not boys. They did wash up well and are soft. I think they are a good deal as well. Too bad they left such an alarmingly deep mark. I gave them to the Salvation Army.

Ex Output:

negative
