A great cushioned race shoe that's meant to go fast. The shoe's drop is enough to encourage a forward motion, which feels great and keeps you off your heels.  The shoe has a good balance of cushioning and responsiveness. I use it primarily for marathons and the cushioning holds up throughout while also offering good road feel.  I used them for a PR at Boston this year. Love this shoe. I would order a half size larger than normal. The toe box is slightly larger than the MR1400's-my previous shoe. I'm 6' 175lbs.
