I ordered these boots with some concern due to the low price compared to the high end brands at WorkNGear where I purchase all my work shoes from. I work in the construction inspection field and have to be in the frigid cold all day at times, in wet and very cold conditions. I used to put the hot hands foot warmers in my older work boots and it would be fine for an hour and then I start feeling my toes freezing up. These boots are by far the most comfortable and kept my feet very warm through the whole 8 hour shift. Definitely would recommend for the price, quality, and quick shipping. Overall great product.
