I have owned, loved and worn two pairs of the previous version of these boots. Ultra 3 exceeded all expectations. Requires minimal break-in, a perfectly customizable fit, and breathable, waterproof performance as before. With the Ultra 3 I have better grip, especially on the descents. They are as light as I can imagine full boots. I have ridden many miles in the Rocky Mountains and the Ozarks and these boots are the best I have ever worn.
