Comments: I've had about 7 pairs of the Nimbus over the last several years, and they have been great. Cushioning has saved my old knees, which used to suffer when running higher mileage. I'm currently wearing my first pair of Nimbus 15's. They feel even more cushioned than previous models. The toe box seems roomier as well, almost too much space for me. The soles on the 15's have worn through much faster than on the previous three versions. At less than 150 miles on the shoes, the right shoe has already worn through the outer layer of colored sole material and into the black layer below. This is twice as fast as in previous versions, and I don't think I've changed my foot strike. I hope that this is an anomaly, and I intend to order another pair.

Comments: Great, cushioned, neutral running shoes and a huge improvement over the 14 which lacked forefoot gel. Shoes heel drop at 10mm feels good, the materials are premium (far nicer than the Cumulus), the tongue nice and big and it feels like slipping your foot into a pillow. Thankfully, the ride is still pretty responsive for such a cushy shoe and they breathe and dry out well. For 8mi+ runs these are a great choice and they seem to be holding up well after 110 miles so far, I'd expect 500-600 before the outsole and/or cushioning is shot but we'll see. Nice job Asics!

Comments: This shoe is a material change from previous versions. Overall 11 was my favorite, and starting with 13 the cushioning got worse. Asics tried to make up for it with these 15's with better cushioning including more gel, but they did this and then lowered the drop by several millimeters. I am a heal to sometimes midfoot striker with flat feet, but use neutral shoes. The heel to toe transition on this shoe is one of the worse that I have ever experienced. I run significantly slower in these, on the order of 30 seconds per mile owing just to the shoes. I need a neutral, but this is not the one.

Comments: Feels like what a nimbus should feel like!! The 15's have the ride of the 14 with the cushion of the 13. Well done Asics!!
From: Mike, Louisiana
Comments: I'm 6'2", 200lbs, run 12-20miles week. I currently use the New Balance 759 and ran my first run, 4 miler, in these 15's. Heel cushion about the same feel, remembering the NB are at about 200 miles or so broken in. The 15's forefoot is much more cushioned and has a nice heel cup. The weight is similar. The toe box is open and almost too open for my foot in the regular width. For the price I would have expected a seamless sock liner in them. The positives outweigh the negatives, so they are a go for me.

Comments: I was running in the New Balance 411 and had worn the shoes down somewhat when I started having trouble with my knees after runs. I read several forums and watched several videos on running and the contributing factors to the various hazards of using worn/improper fitting shoes. I bought the Asics Gel Numbus 15 and couldn't believe the difference in the comfort level. It kinda felt like putting small pillows around your feet and actually enabled me to increase my range as a result of the absence of knee pain. I bought the Black/White/Royal color and my wife wishes there were a women's pair of the same color. I won't even complain about the price due to the fact that Running Warehouse was cheaper and offered free shipping. You can't ask for much more than that in a shoe and a business. Fine job to both!!

Comments: Nimbus 15 feels a lot like 11, 12, and 13. 14 was lacking gel in mid and rear. 15 is a very nice ride. I can easily log 500 plus miles on this shoe. The outsoles will wear out before the cushioning. Weekly mileage varies from 12 to 18 miles, and I have high arches. The sizing down was not an issue but required per manufacturer. I normally do not wear socks also. The lime green color scheme is nice but not over the top.

Comments: This is a continuation of the previous post. I did my first run in these shoes and they have excellent cushioning and shock absorption. I am 6 foot tall and weight 245 and these shoes were like running on a cloud even at my bodyweight. As far as the size goes, these do seem to run a slight bit big but that turned out to be perfect for me. Since running in these I can now tell that my Brooks were a little on the snug side. I would definitely recommend these running shoes to anyone seeking a neutral, shock absorbing, extremely cushioned ride. Hope this helps.

Comments: My previous running shoes were Brooks Defyance 5's in size 12.5 length and 2E width. I just rec'd these Asics Gel Nimbus 15's in size 12.5 length and 2E width today. They fit me perfectly. I kept brain-storming about what size to get. I used shoe-fit-r and that definitely helped. I kept reading about how these shoes ran big but they fit perfect for me. If I had bought the regular width since it said they ran big then I would have had to ship them back for the 2E width. Also, I am a heavy runner. I am 6'0" tall and weigh 245. I will post in the future about how the shoes hold up.

Comments: Unfortunately, fit problems made these a no-go for me. They run long and loose, but not so long that you can size down effectively.
From: Marco, Tustin, CA
Comments: I have done 2 runs since receiving my Nimbus 15s from Running Warehouse and love the extra gel in the forefoot. Asics Nimbus are the best from the 11's through the 15's for me. I am 6'0 and weigh 202 and the Nimbus have the cushioning I need.
From: Bill, Hot Springs, AR
Comments: Great shoes, took them out of box and ran Cleveland Marathon. I know you shouldn't do that, but my 14s were shot. Great comfort, no blisters. Best Nimbus in a few years.
From: Jerame, Newark, Ohio
Comments: I've had the Nimbus 15 for about a month, run about 25 to 30 miles per week and put these through a few 9-10 miles runs (mainly alternating between the 13's and 15's). The cushioning is great and ride is super smooth, worth a bit of extra weight. I have the Nimbus 13's and prefer the 15's - a bit more room in the toe box and they just feel more comfortable when running 6 plus miles. Overall this is a great shoe, I would buy these again. Note: these do run about a 1/2 size big as a few have commented so order accordingly, I've used the shoe fitter for these and the Saucany Kinvara 3's, and shoe fitter tool works great.

Comments: I bought these about a month ago, the 15 is better then the 13, improved fit in the toe box and more cushion. I run 4 to 10 miles per run 5 to 6 days a week (25 to 30 miles per week). Last Sunday I took the 15s on a 10 miler, the 15s were smooth and plenty of padding for the whole run, felt really comfortable on the feet. The shoe does run about 1/2 size bigger then other Asics (13's, 2000's). I don't find the weight of the shoe to be an issue, it's a good trade for a smooth ride. I would buy the 15s again, a great trainer and great comfort on the long runs.

Comments: I love these shoes! 13.5 2E perfect fit, awesome cushioning. the best shoes ever
Comments: So far so good!!! I am a true fan of Nimbus. I have tried most max cushion/neutral running shoe brands and Asics just work for me. I run 15 to 20 miles per week, monthle 5K-10K's, and 3-4 to half marathons per year and love the cushion Nimbus provide. I do miss the offset lacing of the 12's, could not run on the 13's, 14's were OK they took some time to break in and did not provide enough cushion much beyond 300 miles. NOW the 15's seem to be major cush, wider toe box from the 14's, were ready from the first run vs. "break in time" of the 15's. I have the Lt/pnch/Marigold color-- I like orange! So simply, I am very happy with the Nimbus 15.
From: Lisa, Michigan
Comments: The nimbus 15 is a good shoe. It fits better than the 14 did because it has more room in the midfoot area. When running with the shoe you can tell it is heavier than the last two models. I think it has a lot more support because of this. For a runner with more body weight it is a great shoe. The size of the shoe fit me just like the last ones did.
From: Brandon, Kansas
Comments: This is an updated review on the Nimbus 15s. I originally noticed they were sized longer than prior versions, but questioned whether I needed to size down. After a few more runs in them it became increasingly apparent that I needed to size down. I exchanged for 1/2 size smaller and they fit much better without feeling tight at all. Sizing down 1/2 is the way to go with this version.

Comments: The Nimbus 7 was one of my favorite shoes but subsequent versions were nothing like it (the Excel33 1 is the closest I've found). I tried the Nimbus 10 and found the upper to be too stiff, the midole to be too inflexible and firm yet unresponsive, and the ride to be quite unsmooth. I didn't bother with subsequent versions since they didn't seem like enough of a deviation from the 10. This one is quite different. I found the cushioning and responsiveness of the Nimbus 15 to be superior to both the Glycerin 10 and Vomero 7. If I were a bigger runner I'd definitely prefer the Glycerin, though. The Glycerin is definitely smoother but less responsive. It also has more of a glove-like fit which I don't prefer in a training shoe. Between the Vomero and Nimbus, the Nimbus has a more comfortable fit and flexible upper.

Comments: I thought these were the cream of the crop for a neutral high milage trainer. I was tired of putting in 20+ miles a week on my Kinvaras. Turns out I was seduced by the looks. Blisters on top of blisters and a bloody heal after a week's worth of runs. I sent them back. Not sure what happened.
From: Kurt, Yukon, OK, USA
Comments: The Nimbus 15 in my opinion is an improvement over the 14. Issues with the tongue of the 14 have been resolved in the 15. More padding was included through the length of the tongue and the bottom of the tongue is visibly redesigned to eliminate the pinch. The heel cup and arch wrap are similar in feel to the prior version while there is more volume in the toe box. The 15s may be sized slightly longer than the 14s. Depending on your foot size you may or may not want to size down. In my case I believe sizing down would be too tight. Cushioning is better, especially in the forefoot. From the side view, there appears to be more gel units. The 15s also feel more flexible out of the box than the 14s. As a mid-foot striker, I like the ride and responsiveness of the 15s better than the 14s.
From: Howard, Cincinnati
Comments: What a disappointment. I have run in Nimbus exclusively as an everyday trainer and thought that the 14, although a bit heavy, had a great fit and ride. I bought the 15 and they run big, feel not like a running shoe and is way too heavy. In addition the colors are awful. I returned them immediately and got the cumulus 15 which feel much more like a true running shoe.
From: Pauli, New York, New York, USA
Comments: I completely agree with the comment from Anonymous. Unfortunately I'm hoping the "generous" fit in the first pair I purchased can be resolved with some lace tweaking as opposed to ordering another pair sized down a little. The Nimbus 15's feel fantastic before you even open the door and didn't disappoint one bit out on the road. I recently purchased every Nimbus 12 I could find, since the 13 and 14 versions were not what I had hoped for. However, the 15 makes up for it. Unfortunately I see many of the 15's being exchanged as everyone settles in to the new sizing. Great job Asics!
From: Mark, Warrenton, Virginia
Comments: Got a chance to try these early. The cushion is substantially improved from the last version. The ride is more flexible and the upper and midsole are very comfortable. The fit is quite generous.
