21 is a huge number for anybody, without taking into consideration a shoe model. This is the 21st (yes 21st!) incarnation of the Kayano. At whatever point you hear over pronation or support shoe, you will typically hear Kayano next. The 2014 Kayano 21 is here, and it now happens to be one of the softest running shoes in Asics’ line-up with regards to cushioning. Furthermore exactly how soft? More than the Kayano 20, and shockingly, more than the Asics Gel Nimbus 15 as well. This feature is the pivotal difference between last year’s avatar and the just released 21. There are some other inconspicuous configuration redesigns, predictable with Asics’ methodology of incremental advancement.

Upper: The upper hasn’t changed much on the Kayano 21 from a material or design perspective. But definitely some updates especially on fit worth a mention. The fluidfit mesh feels great. It stretches and forms to my feet nicely. It is a snug fit, but there is room where it is needed. The lacing is also comfortably snug, it weaves into the tongue on the midfoot. The greatest redesign is in the heel, named the “Heel Clutching System”. Gone is the solidified plastic under cross section and replaced is a plastic casing. Under it is the same delicate mesh that is on rest of the shoe. The plastic secures heel in, however not overwhelmingly so.

Outsole: It is tricky to say whether outsole grip has enhanced, inspite of some design changes. Outsole compound is the same – blown rubber in the forefoot and carbon rubber in the back, however the Kayano 21 outsole has been changed to incorporate littler rectangular lugs in the forefoot. Duarability levels stay unaltered, and same for the configuration of plastic midfoot shank. The design promoted heel striking but it was an overall smooth ride thanks to the copious amounts of support throughout. The treads were tough and were able to take a beating, even in bad weather.

Verdict: The Kayano keeps getting better every year. The model improves again this year with added support and a lighter feel. It isn’t a fast shoe by any means, but it can take a beating and keep on ticking. If the price was not so high, this shoe would get a perfect rating but it’s hard to justify spending this much on a shoe, no matter how much tech and improvements there are.
