These are really comfortable shoes! This is my first pair of Xeros but I have worn Merrell sandals before and love them. I live in the far north east and find these shoes the most comfortable in our milder weather, but have worn them well in the fall with a wool/reflective insole; It really helped isolate you from the cold tarmac. Now that it's snowing outside, I use them in the office (after changing my winter boots). I was very happy with how light they are for walks and long days on my feet outdoors or in the office. And when you wear them at night, those reflective straps will shine bright! I am very happy with these shoes!
