I was hesitant to order the 19's. I have the Kayano 16's and didn't think I would find some I liked as well. The fit is "spot on". They are lighter than the 16's and the cushion is perfect! The shoes are very comfortable, the fit is perfect, the lace up is just the right length (tried non some other Asics recently and they were too short). The look is updated. They look great! Not too flashy but stylish. Most importantly they feel great to run in! I love these new shoes!
