I run XC and follow D2 College and have been training a lot so far. These shoes are very reliable and good for training. I'd say I've ridden them about 200 miles and they're still very fast and light. They're losing some firmness, but otherwise they're about the same as mine last time. They really help me stay on my front foot and feel really good on trails and flat ground. If you are looking for a fast and reliable training shoe, then this is your shoe.
