I have been waiting for a product like this to land on my desk for a while; all the women in my family have zombie feet: they move around like living feet but are basically cold and dead inside. I spend six months of the year in double socks trying to avoid the inevitable onset of painful chilblains and can chase my husband out of a room by placing a frozen big toe on any part of his body, it’s like an incredibly lame super power - just call me Captain Frost Feet!
