For 5 years I have been wearing Mizuno shoes exclusively for running because they always fit perfectly and have been very comfortable. I tried them even though they cost a little more than I usually pay. I was not rewarded with this decision. I find they don't fit as snugly as other Wave models I've had. Therefore they appear to be "slippery" i.e. my foot moves slightly even though they are the right size. I also found them less comfortable in general and caused some foot irritation that other models don't have. Next time I'll stick with less fancy but much more comfortable patterns.
