So far my experience with the New Balance 890 with REVlite has been very positive. I've run a total of 130 miles on them over various distances ranging from a 5k race, to a 20 mile long run. The shoes are very comfortable, and provide sufficient support despite being incredibly light.
I'll be running the Baystate Half Marathon next weekend, and will be using them to see how they feel over the distance at race pace. Then, a little over 4 weeks from now, I'll be wearing them for the NYC Marathon. Can't wait!
