I'm not an avid review writer but I must leave this review for these Columbia snow boots. They truly are the most comfortable, durable, temperature-controlled shoes I've ever owned. I bought them for a winter trip to Europe and they by far surpassed my expectations. My feet were always warm but never too warm, always dry, and the lightweight boots were so incredibly comfortable and supportive and looked great with everything I wore. I highly recommend these, they are worth every penny. I'm still wearing them even though the weather is warming up and they are still not too warm. One note: they do run small! I bought a half size up and had to exchange them for a full size up.
