Product Description

Runners seeking high performance need look no further than the new Gel-Kayano 21..

In 1949, Mr. Kihachiro Onitsuka began his athletic footwear company (Onitsuka Co., Ltd.) by manufacturing basketball shoes out of his living room in Kobe, Japan. He chose the name ASICS for his company in 1977, based on a famous Latin phrase "Anima Sana In Corpore Sano," which, when translated, expresses the ancient ideal of "A Sound Mind in a Sound Body." Taking the acronym of this phrase, ASICS was founded on the belief that the best way to create a healthy and happy lifestyle is to promote total health and fitness. Today, ASICS offers a full line of performance-driven athletic shoes and technical active sports apparel and accessories dedicated to bringing harmony to the body and soul.

    Very comfortable until a hole wore through in the heel. Shouldn't happen after 2 and a half months. Disappointed

    If you have narrow feet, these are great shoes with lots of cushioning. If you have wide feet like me the 21s are too narrow and the added material in the toe box makes them a tight fit. If you order these, make sure you get a 2E wide and 1/2 size larger than you normally wear or better yet, just get the Kayano 20s instead. There's extra cushioning in these, but you won't notice it because of the tight fit. Hopefully Asics fixes this with the 22s.

    Finally I found the right running shoes with these Asics. I have really bad flat feet and overpronate more so on the right than the left. I have tried Niike, Brooks, New Balance and also Mizuno Wave Inspires because I get shin splints, hip pain and ankle pain.

    These Asics are everything that other reviewers described. It's like running on clouds and my overpronation is a non issue now. The fit is the same as other running shoes I have purchased. Not big or small either one. I would highly recommend these shoes for runners with flat feet as the arch in the shoe does not dig in to the bottom of your foot and the gel on the outside heel acts like a super "shock absorber" when you land on the outside and roll in. This is a great running shoe and well worth the price. BTW I paid $160 for a pair of Brooks that were not any different than a pair of running shoes you could get at any discount store.

    Asics has hit a home run with these Gel Kayano 21's and I love them!

    Well-designed shoes that offer a very modern look and improve on the Kayano 20 in just about every way if you are looking for comfort. Details and stitching appear to be above the norm. Have only taken them for a short run but they already look to be a better fit than the last '20s' because of the much better padding all around on this second-gen design. For me I need this. I'm 200 pounds and go for some strong runs on different terrain.

    Expertly wrapped up in attractive package that to me is going to be hard to improve. Clearly, if they do hold up, these make obsolete any other pair of Kayano ASICS I have tried. The bottom-end design on these is just superb and a much needed improvement from last year. Of course fit and taste varies so be sure to try them out unless you are confident. I am pretty sure these are meant for people that value some comfort above all in their runs. They are not firm and some runners may not want this softer design for their type of shoe.

    The 21 basically fits my normal 11 size foot perfectly, as opposed to some other brands where I must size up 1/2. Other people seem to vary here, but my foot measures very close to an actual 11 and most 11s fit my foot perfectly, without much room to sacrifice either way. It comes down to personal preference. I prefer a snug fit with no toe touching at all even on hard runs. Too much bigger, say an 11.5, and the whole shoe starts to fall apart for me with too much heel movement, which makes you slide forward easier.

    These are about as tight as normal running shoes are. Possibly too tight for some in the mid-section. They feel like extensions of my foot. I wear 1/4 Thorlos or the like with these and I love them.

    I love Asics and have been wearing them for years, ever since discovering the difference a good pair of shoes makes. I don't put a lot of miles on my shoes, so I was really surprised that the left heel is completely worn out and cutting up my ankle less than 6 months after I bought this pair. I normally don't mind paying 120 bucks for a pair of shoes when I figure they will probably last me a year. I am very disappointed because I will have to throw these out right away because my heel is being rubbed raw by the poor heel construction.

    These are great shoes. They wear great and are my most comfortable shoe. They have outlasted my airmax 14s. This show have turned to my everyday shoe!

    The 20s were perfect running shoes; the 21s are ridiculously tight across the top/mid foot area. Maybe i have a weird foot, but then why did all the previous versions fit perfectly for me. It's a shame ASICS has f'd up these shoes.

    I have a couple hundred miles on this pair at most now. The inside of the heel of one of the shoes has worn through and today I got a large blister about three miles from home and had a totally bloody sock by the time I got home. I've been wearing Gel Kayanos since about version 11` or 13 and they always fit the same, very comfortable but with good support. So I guess they decided to change a good thing and stuff them with padding so only the most narrow foot will fit comfortably. I suppose there is a wider version but good luck trying to find anything but a regular fit at a local store and I'm not risk $150 over the internet hoping they'll fit. Final gripe: the laces are about 4-6 inches too short now for back lacing. It is hard getting them on and off without totally undoing the back lacing. Big disappointment.
