Heated Socks

[buffymad]

I'm suffering with a numb foot (from sciatica) and my foot, especially my big toe and the ball of my foot feel freezing all the time. If I can keep my feet warm I can move my foot properly and the numbness subsides. I was thinking of getting a pair of heated socks to see if they helped while I'm out and about or at work etc. Has anybody bought some that they can recommend? Looked at a few different ones but some bad reviews are putting me off (mainly the ones on amazon!). Don't mind paying for things as long as they work!!
