Returning for it’s seventh year, Mizuno unveils the completely updated Wave Nirvana in the premium stability niche. Mizuno updates their shoes on a two year cycle. That is, shoes get new uppers every year and a total update every two years. The 2011 Nirvana brings a totally new shoe to the premium stability market.

Mizuno Nirvana 7 Upper:
A completely revised upper is included in the Wave Nirvana 7 update. Mizuno continues to expand their Dynamotion Fit principles that seek to match movement of the upper materials with the motion of the foot. Mizuno achieves this by using stretch mesh in the forefoot and flex eyelets to lock the foot into the midsole while minimizing irritation and undue pressure across the top of the foot. Another unique feature is the attached tongue found in the Wave Nirvana 7. Mizuno anchors the tongue to the midsole with two flexible strips of fabric to ensure that the tongue stays put once the shoe is laced.

Mizuno Nirvana 7 Opinion:
Since it’s inception the Nirvana series has been my go to shoe for long distance running. Although I am a not a heavy runner my arches are extremely flexible and I must have a shoe that counteracts some of that flexibility. No other shoe has ever offered the exceptional arch support of the Nirvana series. The Nirvana 5 and 6 used a very stiff wave plate which was excellent for pronation control and a snappier transition but did leave me longing for the softer ride of the Nirvana 4. I am very pleased to say that Mizuno has blended the best properties of the Nirvana 4, 5 and 6 into the Wave Nirvana 7. The shoe runs noticeably softer but still provides top shelf arch support thanks to Mizuno’s more streamlined wave plate design. The deletion of the sensor points really opens this shoe up and reduces the harshness found in earlier versions.

In the past Mizuno midsoles seemed to wrinkle sooner than other manufacturers. This problem has been relieved by the introduction of AP+, Mizuno’s new formulation for midsole foam. AP+ also feels bouncier while still retaining the hallmark Mizuno road feel. AP+ actually debuted on the Wave Nirvana 6 but it seems even more durable and fun to run on in the Wave Nirvana 7.

The Wave Nirvana 7 combines flexibility, cushioning and stability like no other shoe before. The fit is seamless and the ride is lively yet protected. Mizuno made sweeping changes to this shoe and that is always a gamble. However, Mizuno has listened to their customers and again proves that each evolution of their wave technology sets them further apart from the pack.

Asics Gel Kayano 17 Heel:
Rounding out the Sole of the Gel-Kayano are ASICS midfoot stabilizer called a Space Trustic System and a DuoMax Support System for the midsole and a Dual Density Solyte Lasting in the heal and forefoot for improved fit and comfort. This midsole and forefoot cushioning in conjunction with the improved heel cushioning all contribute to a very cushioned and plush ride – perfect for those looking for such a shoe in a stability package.

Asics Gel Kayano 17 Upper:
Contributing to the ASICS Gel-Kayano 17’s improved cushioning is a new ComforDry Sockliner along with a revised upper that still incorporates ASICS Asymmetrical Lacing Design for an anatomically correct lacing system that is intended to follow the foots natural design for an improved fit. The Asymmetrical Lacing on the Gel-Kayano 17’s is indeed unique (although other ASICS shoes have added this feature recently) and is a big differentiator over other running shoes. If in the past the upper part of your foot felt compressed or pinched by the lacing system of your shoes you may find that with ASICS Asymmetrical Lacing, that this discomfort is a thing of the past as this is a very well fitting shoe with a decent toe-box as well.

Asics Gel Kayano 17 Opinion:
Having been around for quite some time, the Gel-Kayano’s have been one of ASICS’ most successful shoes. When it comes to Stability Plus shoes, the Gel-Kayano’s have been at the top of consideration for many runners. Having run in many Gel-Kayano’s from the 13’s through two pairs of 17’s, ASICS has done a very good job of constantly tweaking the shoe and improving on it little by little. While the cushioning of the Kayano’s has always been its strength. With the 16 and the introduction of the Asymmetrical Lacing system, fit and comfort became amongst the best out there.
I would think that there are primarily two types of runners considering the Gel-Kayano 17: 1) Those currently running in the 16’s wondering if this upgrade is worth it, and 2) Those looking for a Stability or Stability Plus training shoe.
For those currently running in the 16, the 17 is definitely an improvement and you’ll love the decreased weight slightly better cushioning and responsiveness. That said if there were close-out deals on the 16’s and you could save some money, I might stock up on some 16s. But if moneys not an issue and you want the latest that ASICS has to offer, you won’t be disappointed in the 17s.
For those considering the Gel-Kayano 17 as a Stability Plus shoe and are ok at parting with $140+/- for a pair, I don’t think you’ll be disappointed unless you are a very light weight runner where the weight of the shoes while improved from the 16s is still a bit on the hefty side and/or if you want a more responsive shoe – which usually means not as plush a ride as the 17s give you.
At 6’0 and 175 lbs running on average of 50 miles a week, I go through a pair of shoes about once every 6 weeks and have already had the pleasure of running in two pairs of 17s and must say they are my favorite especially for that long run or medium long run when you want the most comfortable and cushioned shoe. My 16s have been resigned to shorter runs or trail runs until they wear out
My ‘nits’ with the Kayano’s have been few – one is weight which has been addressed and hopefully ASICS will continue to address this and the other is the breathability of the upper which became a problem on long runs during last year’s hot humid summer. So far no problems with breathability as it is winter so we’ll have to leave the jury out on that one.
Bottom line – If you like the 16’s you’ll love the 17’s and if you are looking for a very well cushioned Stability Plus shoe and are ok with the price – try these on, you may be very very happy!
