These are my second Mizuno's.  My previous review for this line was for Wave Rider, which I am still extremely happy with.  The only reason I chose to "bump up" to the Wave Creation is b/c of the glowing reviews from running magazines on this particular model and they are finally at a price point within my comfort zone!  I say "bump up" only b/c this shoe is more expensive with a little more bounce and definitely more support for my overpronating feet.  Still, you MUST size up ONE FULL SIZE if you run a similar distance (30 miles per week)and tend to swell.  I am thrilled with the "shock absorption" of this model b/c I always felt some back/knee issues when I ran in my previous Nike's.  I don't even HAVE back/knee issues anymore and I can finally keep my toenails even while maintaining my distance. I have the black/anthracite/turquoise color and though they look bigger on my feet than the Wave Rider's did, I'm running by so fast that it doesn't even matter!  :)  I honestly don't need to ever move to another brand of running shoes and I highly recommend Mizuno to other serious runners.
