        I loved Kayano, but the 21 disappointed

        By Claudia

        from Sao Paulo, Brazil



            Best Uses

              I have worn Kayanos since the 14, and have always been the biggest fan. However, Kayano 21 was a very different experience. I trusted the brand so much, that I bought two pairs online. I bought them in the same size as always, but they have hurt the tip of all my toes really badly. I compared them to the old ones, and they are just slightly smaller. I guess the extra cushioning in the heels somehow is pushing my feet forward against the hard tip. The fitting is just not right. Besides, they added this plastic thing where they wrote "fluid fit", which is right on top of my 4th toe, and hurt it a lot, too.
              I went on asics' website to write my review, and learned that many other people who have always worn Kayanos had the same problem.
              Roadrunner was perfect as always, and I ended up returning both pairs (one of them still unused) and getting myself a pair of Mizunos for the first time in my life (Wave Paradox). I am surprisingly happy with them, and now I am just waiting for the return to be processed in order to get a second pair!
              Even if you are used to Kayanos, make sure you reeeeally test them!
              Nevertheless, I am still hopeful that asics will reconsider some of the changes made before Kayano 22..

              Surprisingly uncomfortable

              By Anonymous

              from Boston



                • Causes Numbness Of Feet
                • Tighter At The Toes
                • Very Uncomfortable

                Best Uses

                  I have used Asic's Kayano shoes for many years. Each time a new model is released, I buy those. I have stayed faithful to this specific model but for the first time, I am disappointed. The Kayano 21 is nothing like the previous models. My feet hurt with each workout. After one month and certainly now after 3 months, I am desperate to buy new shoes and will go back to either Gel Kayano 19 or 20, whichever I find! This is a totally different experience with the 21 as if it were a new shoe altogether. Please note I buy Gel Kayano shoes every 6 months. The 21 is the only model that I have found uncomfortable to wear. I hope the next model is like the previous ones.

                    • Running Long Distance

                    This shoe is awesome! I have tried every shoe out there, and nothing compares. I have horrible wide feet and have always gotten blisters when running races. I ran my first marathon in these and was shocked at the finish line, my feet were the only thing that didn't hurt! Not 1 blister! Love these shoes! Also very light weight for a stability shoe!

                    Bad Update for my Feet

                      • Hurt my feet
                      • Lack of cushioning

                      Best Uses

                        I've been buying 1 or 2 pair of Kayano's per year since at least the Kayano 17. They have always given my feet excellent support and cushioning. However with these Kayano 21's I found that they are lacking cushioning in the areas I need it. I wore them to the gym and within in 30 minutes on a stationary bike my toes were going numb. I decided to add some inserts which only helped a bit. I went on a power walk and made it through the first 50 minutes with only a little numbness but the last 40 minutes went from difficult to agony. I had to stop and sit for a bit to get some circulation back in my feet. I also had a spot rubbing on the base of my big toe that I was unaware of until I took off my sock and found it rubbed raw. I never had any issue with the earlier Kayano 17-20's. Unfortunately, whatever they changed in this model is really bad for my feet and there is a pressure point created that cuts off circulation.

                        For once - update is an improvement!

                        I've been wearing ASICS for some time,and switched to Kayano on #19 to get more padding. Also had #20. This update seems to head back to the #19 fit (which I preferred) and is better! Updates are tricky and often make something that works stop working. Glad this one is just better.


                        Great update

                          • Long runs
                          • Short runs

                          I've been wearing the Kayano since the 14 came out. When I heard they were releasing the 21, I had to get them! While I was not impressed with the Kayano 20 (a bit too snug for my foot), the 21 is great! The fit is a lot better, and works with my custom orthodics. I normally wear a size 8 in running shoes, and for me, these seem to fit true to size. They are great for short and long runs; I don't feel fatigue in my feet and knees. Although they are a bit pricy, they are totally worth it! I just bought the Kayano 21 Lite Show, too!!
