Wow, what a cool shoe! I'm usually loyal to the RC1400, but for some reason the reviews and looks of this shoe called my name. God I'm glad I bought them. I used to think I was a minimalist runner, always looking for a shoe with the smallest drop from heel to toe. When I got them I thought I would hate them. On the contrary, I love them! Lots of padding and support but they don't feel bulky like some of the Asics I have. Traction on the outsole is great for running outdoors, but feels like fun on the treadmill.
