I am a walker, not a runner, so bear that in mind. I have overpronation and low arches. My fav shoes recently have been the ASICS GT-2000 8's, but as I can't find them in my size anymore, I did some research and decided to try these. Supposedly, the Gel Kayano series is a step up from the GT-2000. The cushioning is fine, and seems to be on a par with the GT-2000's. It feels a little "different", but not noticeably "better". These shoes are OK and I'll keep them BUT: The color choices are very limited - i had a choice of black or grey in my size. The toe box width is small, and smaller than my same-size GT-2000 (see photo - the black shoe on top is the Gel Kayano). My feet are 4 inches wide, which should be a D width, maybe an E for extra comfort. I bought these in Extra Wide and they are barely wide enough. I measured them across the top and they are 4 inches. A true Extra Wide shoe should be 4.6 inches. They also measure a quarter inch less in width across the sole compared to my GT-2000's, which are the same "size". And lastly, the shoestrings are too short - when laced up there is only about 4 inches left to tie. So, needless to say I am not super impressed with these, especially since they are supposed to be a step up from the GT-2000. All that said though, they fit "OK" and I'll see if I like them more over time, and will update this review if that happens.The shoes are tight around midfoot and took about 15-20 miles of running to break in enough to stop hurting. I didn't want to spend extra money, but I should have gotten the wide version. My main problem though, as seen in my picture in the shoe on the right, is that the achilles padding at the back was put in low. I tried to pull it back up so to speak but it doesn't move. It makes me constantly feel like that shoe is slipping off. I assume it's a rare QA/QC slip up but it's annoying when I paid $80 something for it. They're not bad shoes but I wish I went with something else.I'd been having some heel pain and was told that I pronate when I walk (I don't know if the two things are related). I checked different brands and models of shoes that were good for pronation. I picked these based them being a stability shoe for people who pronate, as well for the style, color, and price. I've only had them 12 days so far but I've worn them regularly and I'm very happy with them and have no regrets about buying them.After years of suffering from sports injuries I realized that I can still do performance training if proper shoe ware is worn. I usually run outside in ASICS Nimbus that provides nice cushioning for my knees and hip joints. This pair of Kayanos is very stable, has wide enough toe box to provide great ventilation for the foot, light enough for a comfort run and looks great. I’m using it for treadmill training only. I use them daily for the last 6months running 3-4miles at a time. I have not taken them outside. They held very well mechanically considering that they haven’t changed much after 600miles on treadmill. I had some hip pain and knee instability when I started training in them half a year ago, and managed to strengthen both over that period of time, no serious injuries. They are not as soft as Nimbus I wear outside for my runs, but gentle enough and predictable mechanically on treadmill when you land your feet during the run. Both Kayanos and Nimbus are awesome to keep your joints injury free. Stay healthy and enjoy cardio!The Gel Kayano is a very comfortable support sneaker, especially for overpronation. BUT -- the 4E Extra Wide sizes are NOT really 4E and are still *very narrow*. I measure a 9.5 4E, but I needed to get a 11.5 4E to compensate with this shoe, and it's still tighter than I'd like.Finding 4E sneakers continues to be a problem, as the only sneaker that fits me perfectly is the New Balance 990, and that sneaker has been extremely difficult to find in 4E since 2020 (in any color other than light gray anyway). I wouldn't buy this Gel Kayano again, but I assume the sizing is correct for normal widths. Just beware if you need 4E.I have been dealing with minor shin splits. The arch support started helping almost immediately. This helped me to be able to run a bit further with little to no pain.This is the 2nd pair I have bought for my son. He loves the comfort of them. At 12 he had a heal problem and his dr recommended this style. Great shoes all aroundGreat sneaker for my wide feet. I use them for work they hold up for 6 months in a tough environment. Im not so happy the seller Asics sent me a non retail box without tags. I would be returning if they were a gift.Excellent, professional communication from the seller enabled a smooth transaction..The trainers fitted perfectly and arrived promptly as quoted.Many thanks for your help and I have no hesitation in recommending your company..Kind RegardsOne on the best asics shoes you can buy in my opinion, worn these for year's and each model always improves. Found them on Amazon cheaper which makes a changeGreat styling, comfort and fit, especially for running with over-pronation - both on the treadmill and outdoors.Gel Kayono 27 great support around gait and very comfortable to run in ?Ho comprato queste scarpe su consiglio ortopedico quando ho ricominciato a correre avendo precedentemente avuto problemi alle ginocchia attribuite a pronazione.Ricevute le scarpe con forma i misura giusta ho iniziato ad usarle con risultati pessimi, molta più fatica del necessario e dolori forti alle ginocchia. Incuriosito ho controllato le scarpe attentamente e ho trovato le rifiniture di qualità pessima, il che mi ha fatto alla fine decidere di chiedere il rimborso. Devo ammettere che nei giorni successivi ho controllato lo stesso modello in alcune catene di articoli sportivi e devo riconoscere che la qualità fosse ugualmente scarsa anche qui. Quindi non un problema di originalità quanto di scarsa fabbricazione per ADIDAS.Per quanto riguarda Amazon merita 5 stelle per la comprensione, l'aiuto e il rimborso solleciti. Servizio di prima classe e il giudizio basso è solo relativo alle scarpe, non al fornitore.
