I run regularly in the Mizuno Wave Inspire 11, and needed shoes for a Ragnar Trail Run. The Hayate shoes of the same marked size were significantly smaller than the Inspire: much, much narrower at the ball of the foot, and the fabric across the top was prohibitively tight for me. Mind you, I don't have particularly wide feet, but I couldn't run more than a few steps in these because it was so tight across the top when pushing off. Also, although the information I found said this was a &#34;stability&#34; shoe, it still had a lot of torsional flex and the footprint is very narrow. I will buy the Inspire again, but returned the Hayate: it may be a great trail racing shoe for someone, but not for me.
