I have Brooks, Nike and Asics. The Rebel v2 is by far the best fit of all, you don't have to buy the shoe a size up. The propulsion is fun, a dream for middle and front foot runners. The shoe is very performant and comfortable, especially for fast runs, but is also my favorite for slow runs. I've run 400km in the shoes so far at distances of 5 to 19km and a pace of 4:20 to 8:00. I got a second pair. If a shoe fits so well, you should buy in reserve right away
