The Kayano 28 is meant to be a shoe with stability. Not all runners are build the same nor, importantly weigh the same.I'm a 5 foot 6 inch 120 pound male, athletic build with a running back ground in track and cross-country running. I over pronate in both feet and more so in my right. My left foot is almost neutral. This gives me the advantage of seeing how shoes may work for both neutral runners and those who pronate.It was a hot, dry day when I tested the Kayano 28 on asphalt, concrete, hard dirt, grass, gravel-covered ground, a wooded trail and on a running track. Oh, and on some stairs for stair work- more on that later. The Kayano is a road shoe first and foremost but can handle some light trail work.The shoe performed pretty well on all these surfaces but less well on gravel and it was a no-go on sand. No surprise there. it did okay on the light, groomed trail even as i was looking for rougher patches. it is a no go on technical trails which is no surprise. And on stairs ... wooden stairs with good grip and nothing spaced too far apart. metal stairs are a straight out NO- that is super dangerous and you will have zero traction. It may look cool to do cardio on stairs to feel like Rocky Balboa but these shoes will not allow you to gain purchase on certain kinds of stairs. For your safety, unless you got mad skills and a wish to break something, do NOT try running up and down stairs in the Kayanos. Walking- sure but be careful and aware.From experience, I am not sure how this kind of traction would do in wet conditions. the tread on the Kayaonos is pretty minimal and even tough it's AHAR, a fabulous material in its self, the tread design is best for flat, dry roads and other flat, even and dry, non-slippy surfaces. Did i repeat my self there? ....While the cushioning on the shoe felt nice after so many denser stability shoes i've had, it was a bit too cushioned and there was not that much springy-ness as well. When i ran on the track, which was a softer composite surface, it was like running on double cushioning which sounds nice but highlighted the shoe's biggest weakness and potential danger.it may be because I weigh only 120 lbs that there was not enough weight pushing on the cushion, but, this shoe was very unstable despite all its technology. I had to be very aware of how I placed my feet as I went trough my gait cycle or the mushiness would cause me to roll an ankle. I tested them in all sorts of running modes, postures and techniques, etc ect - I ran track so basically did every kind of running style in them to test them out. This said, I decided to at some points to just "trust" the engineering and run with out thinking about my motion. the shoe in this case took over and did surprisingly well despite being unstable. Doing this was risky and I felt that after a while the luck of it may wear off. and, in fact i had strained my ankle and Achilles tendon by the time I was done. i did not fully roll my ankle but repeatable came close.In many ways I should have known better. When i first put them on and stood up, I stumbles side to side as if the side walls of the mid sole were giving out. i have very good balance so this surprised me.After my test run, my left foot felt soso, not great but soso. My right foot, the one that pronates more, was not faring well as it was the ankle I had nearly rolled multiple times. it took a few days for my ankle to recover but it could easily have been worse.Breaking the shoes in would have no effect since the Kayanos are so soft as is. it was like running on marshmallows. While I can see potential in the 28th iteration, Asics needs to take more time to refine this shoe to be safe to wear for lighter runners. For that, it needs to be less mushy and have a lower heel drop - that is the difference between the front stack height and the rear stack height. It would also help if there were a bit more spring or responsiveness in the shoe as well. The tread is almost too thin and could use a bit more. If the traction were a little more regressive, that'd be a nice touch.In the end, I cleaned them up and sent them back.I first bought a pair of these shoes at my local running store. I have a wide foot, so the 10 1/2 D width felt too tight; I went with the 11. I wore them well for a few months till they started to break down from use, which happens to all shoes. So, in order to get a different color, I shopped at Amazon and order the exact same size, 11-D. Too big! Who'd have thought that two of the same model shoes would fit differently when the only change was the color? I noticed it the first time I used them, but I wore them for about three 5-mile power (fast, but not jogging) walks hoping they'd feel better. They didn't. So, I returned them for a full refund. Then I ordered the 10 1/2 wide and, voila!, my feet are happy again. I've used them on two power walks. They feel pretty damn good! So, I'm glad I didn't give up on the brand and style. I love these shoes. :)I like the fit of this shoe, so hard to find an extra wide shoe in my size. overall this shoe hits the marks in fit and stability. The cushioning of the shoe is plenty ample as well. My only real pet peave is that these shoes break down too quickly. My pair from three years ago still has some life in them, but the pair I bought last year didn't even last the year. The foam that gives that great bounce to your step doesn't last. With this year's model I find it's already begun to show wear. The black rubber used on the bottom covers less of the shoe's bottom. I get that they are trying to save weight on the shoe, but in my opinion, they've gone too far.Size fits true for me, I continue to purchase Asics as they have a 12.5 mens shoe that fits as should every time. These were purchased for work, hospital, they match my scrab color exactly! The comfort is as I expect, wonderful for 12 hour shifts. I do a moderate amount of walking with standing. I feel as supported as usual with all my Asics.I ordered these as they were rated as one of the beat shoes at alleviating and preventing plantar fasciitis. I had owned a pair previously and they worked wonders. The pair I just ordered were everything I expected. After a month of wearing them, however, the rubber on the bottom started to detach. This wasn't a huge issue, as I simply glued the rubber back in place, but it was a flag for me. Preventing a perfect 5 stars.These shoes are so comfortable and they look as good as they feel. If you run 10K's a few times a week I highly recommend you buy these shoes.A little narrower than expected but still fits. I can run with minimum plantar fascia irritation. Extremely light - feels like it shouldn't cushion, but it does. My only regret is not having bought it in 13W. Let's face it - most Size 13 peeps have wider feet as well.The extra width is important and made this a good buy for me. Also, the cheap insole is removable and can be replaced with an orthotic arch support, also important.El producto es muy bueno, la publicación es la que tiene mal las características.
