This is my 4th pair of ASIC Noosas. My first 3 pairs are Noosa 13s and I just received my first pair of Noosa 14s. There are some subtle differences for me. I find the back of the heel is a bit more rigid but I think after wearing them a little while that will soften up. The arch support does not seem as pronounced in these shoes but overall they are very comfortable! I also feel like the tie box is not as roomy as my Noosa 13s….. I love the color combination for wearing with my scrubs but I do wish they would make the same shoes in a neutral color for weekend wear. I have had Achilles surgeries on both feet and a left knee replacement and I have found these are the only shoes I can wear all day long that do not cause pain! The lower heel drop makes a lot of difference for me in not putting strain on either the Achilles or the knees. I constantly get compliments on them too so that’s an added bonus! I do recommend going up a half size as others have suggested, they do run a little small.
