Title: Not worth the purchase
Review: I got these for my husband whose a tank wagon driver delivering fuel throughout the winter months in Iowa, he tried them out and was very disappointed! He said that they shifted in his boots and wouldn't stay in place on top of just not working to keep his feet warm. It hasn't been an extremly cold winter but it's cold enough for him when he has to be in cold most of the day. He definetly doesn't recommend these and suggests that you don't waste your money trying this method out!
