Who knew Mizuno made running shoes?  Not me.  I was at my local RoadRunner and tried on at least 10 pairs before these were brought out. I was surprised to see Mizuno since I only knew of them as a baseball brand.  I was in the early days of training for a half marathon and my old Sauconys were not going to last much longer.  As soon as I tried these on I knew they were the one.  Here's what I like about the shoe (keep in mind this is coming from a complete novice to the running world):

-they provided just the right amount of support for me. I am not a fan of shoes that are too soft/"cloud"-like or shoes that have a stiff sole
-the shoe does not have high side support (on the outside of the shoe beneath the logo).  I am a size 5 and have a wide foot so shoes with too much side support cause pain after long distances
-obviously the color is great and super fun!  I actually had the black pair first but once I got home and saw the blue pair online I quickly exchanged them
-they are light as a feather! I enjoy wearing them while I'm out running errands, too.

Note: as another review stated below, the stock photos aren't a true reflection of the color of the shoe. The photos show more of a sky blue/periwinkle whereas the actual shoe is a vibrant bright blue - think somewhere between Robin Egg Blue and Cerulean from the Crayola box.  Yep, I just went there.
