I had over 450 miles in the MR10 and decided to try out the MR00. It's too bad they discontinued the MR10s for this model, they were much better before.  I loved the MR10s and was very optimistic about these; however, was let down by the fit and quality.<br /><br />The MR00s are much more narrow everywhere except the heel. Having ordered the D width first and being too narrow, I tried the 2E width. My heel was slipping out of the shoe but the rest of it fit my foot nicely. New Balance made the heel wider and the rest of the shoe much more narrow.<br /><br />Also, mine had a thick overhang from where the side of shoe met the sole, along the inside heel area of shoes (see photos). Also had some wrinkling on one of the shoe's soles at the heel. Overall, very disappointed with the quality. It should be seamless in these areas.<br /><br />Not sure what to recommend other than finding a different shoe.
