I was wondering if anyone has tried the elastic ankle braces you can buy at any drugstore. I found these give me some relief, and after reading about the Sock, I can sort of see why. They support my weakened ankles, they provide a slight massaging action, and the strap that fits under the arch helps support it. The tightness of the band helps a little with keeping your foot from flopping.
I thought that folks who found the Sock was interfering with sleep might want to try the ankle brace. I don't think this could harm a person's foot, however, I am not a doctor so use at your own risk.
