I have never written a negative review before, but this product deserves it. I have a pair of mizunos that I ordered from their actual website and love them. I chose to order these shoes from Amazon, as I am a prime member and get free two day shipping. I chose to ignore the negative product reviews and buy the shoes anyway. Just so all the info is out there, I ordered a 7.5  because the brand runs small. I typically wear a size 7 and have a narrow narrow/flat foot. As one reviewer stated, the shoes do have some sort of Chinese/Japanese symbols on the side that my previous mizunos do not have... Another reviewer mentioned the inside top/tounge portion of the shoe was rubbing the top of their foot. The same thing happened to me during my first run with these shoes, causing me to be very uncomfortable ...  I thought maybe I needed to wear a thicker sock next time I ran in them. I tried out a second run wearing a thicker footie sock and felt the shoe rubbing at my heel... I took the shoes off and had already developed blisters on my heel only the second time ever wearing them. I also noticed that the top portion of the laces on the two shoes are not symmetrical. The left shoe laces are straight and the right shoe laces veer to the right. If you look closely at the picture I have posted, you can see the top right lace is almost diagonal and the top left lace is straight across (my ankles and feet are together in this photo). That was enough for me and I decided to return them. I wanted to like the shoes so bad because I LOVE the mizuno brand. This product, however, is NOT the same mizuno quality that is deserving of a $109.00 price tag. I don't believe these are real mizunos considering all of the trouble I've had with these shoes. As a runner, the quality and science behind a shoe is very very important to me. This just is not a comfortable shoe for running or anything to be honest. It could've just been that my foot type and this shoe just don't mesh well... But really a RUNNING SHOE shouldn't be this uncomfortable no matter what kind of foot you have loly a RUNNING SHOE shouldn't be this uncomfortable no matter what kind of foot you have lol
