This is my fourth pair of shoes bought from Xero Shoes and I love them. I first bought them in anticipation of snow/ice skating in Chicago this winter, but I quickly realized that they are much more than just running shoes. Yes, they're great for winter running thanks to their profile, but they're also great for running on flat, regular asphalt. They're just as flexible as their other models, just a little thicker to accommodate the tread on the soles. They are also great everyday shoes. The upper is very comfortable and warm and since I bought them I've been wearing them for business more than any other shoe.
