The Dyad 3 was great for me. I'm a long time Dyad runner, very flat footed. The 3's felt as soft as they ever have. It didn't matter if it was day 1 or day 60, they felt great, always very cushioned. I ran them on both trails and roads, no problems. I'm hoping that future models have a more open mesh upper. This is without a doubt the shoe for flat footed neutral runners.
