Comments: Absolutely amazing shoe!! I bought these for NYC and Boston. Raced them for the first time last weekend in a 15K training race. Knocked 3 minutes off my old time and clocked a negative split 55:06 with much to spare at the end. Also negative split a 24 mile training run 2 weeks ago. Easily can handle marathon distance but can also be used for 5K's. If you ask it to turn over quicker, it does so effortlessly. I strike midfoot to rear midfoot. The ride is a bit softer and much better than the A5 (which I would never use for a marathon). The fit is slipper-like with a somewhat wider forefoot (almost feels like it's not even there). I did size up from an 11.5 to a 12 and it's perfect. I'm 11.5 in Saucony Virratas and Asics Gel Lyte 33's. 12 in A5's. I have burned through A LOT of shoes over the past 5 years and these are hands down the fastest and favorite shoe I have used to date. Ordering 3 more pairs before Asics changes it again.

Comments: Great Shoes. I have use nimbus 13 for my race shoes but was looking for something better. These are the best for races. They are light weight and get support for me. You have to buy a 1/2 size bigger though. I use only on races and they feel great done 5k and 10k on them. You can not bet the price :) Worth Trying!

Comments: After running in this shoe all summer, IË™m ecstatic this shoe is back and would love to see it continue. I find this a great looking shoe built perfectly as a comfortable, lightweight racer built in the mold of the 3, 4, 5 editions. However, I do miss the more substantial structure as well as ideal weight and sole density of the older models for everyday training. I would be great if Asics could reissue a new version of the old shoe with the same past specs in heel height, weight and density for this purpose. Still a great shoe for racing, just haven't found an ideal replacement for training.

Comments: Bought these shoes from LRS with a gift cert from a race. They felt pretty good in the store, but turned to mush when I tried to run in them. Way too soft for my liking and they have been designated as lawn mowing shoes after about 30 miles of trying to run in them.

Comments: Nice shoe I use for tempos and races 10k-Half Marathon. 6.8 ounces for my 12.5s I notice it takes a couple short runs to break them in but after that they feel great.

Comments: Fantastic shoe in itself. Unfortunately I am at just over 100 miles on these and the mid/forefoot tread is already starting to tear apart down to the white foam. I'm a little rougher on my shoes than most and I never expect to get 300+ out of them, but under 150 miles? As someone else said, maybe these are a "Race Only" flat. But for me personally, I like to get my Workouts of Substance (Pace, Tempo, Speed, Long) done in something that will callous my feet and legs a little more to prepare myself for race day.

Comments: This shoe in my opinions IS the BEST racing flat out there. It is extremely lightweight for a half marathon and marathon shoe which makes it great for the 5k distance as well. I've done a lot of my tempos and races in this shoe and I will be buying another pair because it has become my favorite shoe. If you're someone like me who has a wide foot and needs to put and insole in your shoe for arch support then buy this shoe a half size larger because this shoe is a little bit on the narrow side. Overall this is the best shoe from distances from the 5k all the way to the marathon. I promise you will love this shoe. It has become my go to racing and tempo training shoe. I give it 5 stars with 2 thumbs up.

Comments: First off let me say, I have No regrets buying these. As far as size I wear a 11 and the 11.5 fit me perfect so order at least a .5 size larger than you wear. These shoes are very light yet have what feels like a lot of cushion when running on concrete. I was shocked at how soft they felt without sacrifice in support. This is what I consider a race shoe only though. The uppers are very thin material and I'm scared they might not last too long, but I like them so much I'm ordering another pair so if they do fail I'll have back up. So if your looking for a comfortable race shoe look no further. I Am a fairly novice runner and run in 5k and sprint triathlons. My last two previous running shoes have been gt-2000 and guide 5s. Which I will still use to train in, but come race day the hyper speed 6 can't be beat.

Comments: What Ed said... He pretty much described my experience, running solely in the Hyper Speed 3s, 4s, and 5s. I like the comfort of this shoe over the previous models since the 3. My first run in the new shoes was a 10k race; I ran sockless and had no problems whatsoever with my feet. Anyway, glad too that it's back as I couldn't find a good replacement.

Comments: This is a narrow shoe. It also fit a little smaller than the running warehouse shoe fitter put me in. Make sure you go a half size bigger. I have 25 miles on them and I'm done. They were just too short and too narrow. I should have returned them but I tried a run without socks and another run without the soles.

Comments: The greatest running shoe ever made is back!!! I have been waiting for this shoe for months as I am down to my last pair of Hyper Speed 5s that I stocked up on. For starters, the same differential of 6 mm is unchanged. This has always hit a sweet spot encouraging proper mid/forefoot strike while allowing for some slop in longer mileage for calf and achilles relief. Improvements include a seamless upper along with a significant drop in weight. The outer sole design has also changed so trapping small rocks is no longer an issue. Also, Asics has knocked it out of the park aesthetically on this one. They just look AWESOME!! Now for the constructive criticism. One of the features that made the original Hyper Speed such a special low-profile shoe was the softer outer sole material. This allowed for a much softer ride than you would expect from a flat. The newer outsole is made of a more durable plastic which will probably last longer but I was ok with buying a newer shoe a little sooner for the unique balance of comfort and proprioception on the previous models. Also, Though I think the upper looks terrific, I felt the previous models felt more comfortable and a bit more supportive. All in all, it‚s still the best all around shoe on the market and I‚m glad it‚s back.
