Asics Gel Kayano 16

This had to be one of my comeback posts because as a marathoner, I was beyond pleased to finally see John in some good quality running/workout shoes - assuming he was working out?
I don't know if they were chosen for style, quality, or both, but I'm going to give Mayer the benefit of the doubt and guess that he was smart enough to know of the quality of Asics relative to working out.
In my opinion, if you're not a minimalist runner, Asics are the best quality running/workout shoes one can buy. I've worked out, ran, and still train in nothing other than Asics and they've treated my feet very well over the years. This includes a Boston Marathon. The Nimbus work for my feet best. The Kayano are one of the top of the line Asics, though are not rare, and can probably be purchased somewhere online, or at your local running store for somewhere in the range $140.
