I have worn ASICS Gel-Kayano runners for almost two decades, having owned at least one of every version since I first started. I'm giving these two stars ONLY because they are better than the 22s, which had a toe box that was so narrow, they were unwearable.

These are marginally better in the toe box width, but there's less vertical room in the toe box, giving me blisters on the tops of my toes. There's also something weird going on with the arch, as it has rubbed blisters into my feet at the back of my arch, right where it meets the inside of my heels. I've had to tape up my feet before every workout, which is ridiculous with top-of-the-range shoes. I persisted, as I figured they would eventually wear in, but they never did.

After struggling with 23s for a few months, I've now got a pair of 24s and hallelujah, the fit is back! The 24s are comfortable like slippers, with a more cushioned ride. They were amazing right out of the box. Skip these, buy the 24s.
