Debra Weitzner Thermal Socks For Men Women 4/6 Pairs Thick Heated Warm Winter Boot Socks - Insulated Extreme Cold Weathers

Is there a warranty on these socks? The description says I’ll never have to replace them, but what if I wear a hole in the heel?

Is this 6 pairs or 1 only?

It looks the the washing instructions say you cannot put in the dryer, is this true?

I am trying to order "Mens" socks but when it gets to my cart for checkout, it says "Womens" socks. Can you please help straighten that out?
