These are wicked light, and very rigid. I bought these because Backcountry had them on sale and I needed a new pair of shoes. I was so impressed after using these that I am debating buying another pair. They are very light and super rigid which makes a noticeable difference when riding. They are definitely summer/spring/fall shoes, not winter. They are very breathable, which is good, but when riding on a frigid winter morning, your feet will freeze. I just bought some shoe covers, and voila, problem solved. You won't be disappointed with these.
