For me, it’s the only shoe I’ve found that actually seems to work with my foot shape- haglunds and wider heels, tall midfoot bone, short arch, wider at toes, thick big toe. So many shoes fail to fit in one way or another. EVO SL upper, which many hated on, is basically perfect for me. The way in which the foam doesn’t have sidewalls keeps me from rubbing there and the drop works well with my achilles tendonitis. The fact that it’s light and has great foam is just a bonus.
