I am trying the put water in a ziplock bag, stick it in your shoe and freeze it trick! I have heard many reccomendations for this trectching trick, thought I would give it a try. Was still skeptical but Neo girl said her grandma use to do it, so I figured a grandma trick was worth trying! I just hope hubby does not find it, I put it in the one in the garage so hopefully he won't!! I will let you all know if it works!! Keeping my fingers crossed.
