Hesitantly ordered these for my 9yo son before a week long deer hunting trip. Temps from low 40’s to mid 70’s. First morning put toe warmers on his feet, second morning he asked to not use them and it was colder that morning, he said his feet have never stayed that warm. We walked overall around 10 miles he stated the boots were much more comfortable, lighter, and warmer than his previous other name brand insulated boots. My muck boots fell apart on the trip so I will be buying myself a pair.
