The Gel-Hyper Speed 4 is a minimum feature, moderate neutral shoe designed for speedwork and racing. It is built with a semi-curved shape.


  • Rearfoot Gel cushioning system is a silicone based gel that attenuates shock during impact.
  • SpEVA is a full length midsole material and is Asics' mid-level midsole. Although SpEVA is not as durable and lightweight as Solyte, it has increased energy return compared to that of compression molded EVA.
  • Magic Sole is a vented misole to minimize weight and increase breathability.
  • Racing Trusstic System is located at the bottom of the midsole and is made from thermal plastic. Its lightweight design allows for faster turnover while still maintaining torsional integrity between the rearfoot and forefoot.
  • Open mesh encompasses the majority of the upper and offers breathability to keep the foot cool.
  • Asics logo is located at both the medial and lateral sides of the upper to keep the shoe snug to the foot.
  • Standard sockliner
  • Slip Lasting involves wrapping and stitching the upper in a bootie-like shape before it is glued to the midsole to increase flexibility and decrease weight.
  • Asics High Abrasion Rubber (AHAR) is located in the heel and is a carbon rubber that offers exceptional durability.

Customer Reviews

Comments: I had been running in Adidas Adizero Rockets and looking for a marathon racer as the rockets tend to be too firm for that distance. I picked up a pair of Nike Lunaracer 2 and then picked up these on clearance from RW. Let me start by saying I really wanted to like these shoes. I probably only have 4 or 5 runs in the Hyperspeed, about 30+ miles. I was surprised at how substantial the Hyperspeed upper is. Impressed at first, but one annoying part is the heel. Where the Rockets are smooth with no seams there, the Hypspeeds have seams there. I felt some irritation initially, but it seems OK now. My other initial impression of the Hyperspeed is that its ride is surprisingly clunky. It just doesn't roll well, and doesn't feel fast. I feel like I'm getting nothing back from the shoe; it feels like it's clomping along.

The Hyperspeed have a wide toe box (which I like) but the heels seem also a little bigger which I don't like. (I am 10 in Hyperspeed, 10.5 in Rocket.) I thought the clunkiness might just be that they need more breaking in, but it hasn't improved. I am also very disappointed in the wear. After the few miles I've put in these they have almost as much wear as my Rockets with hundreds of miles on them. One last thing - I've run in other shoes that have holes in the tread, but this may be the first which has holes under the ball of the foot. I've already got a little sharp rock lodged in one that I had to stop to take out because I couldn't run it out and it hurt and also have hit another rock that didn't lodge in the sole but that I felt through the hole as if I was almost barefoot.

I'll see how these develop, but right now I can't say I like these, even at the clearance price. I hate the flywire in the upper of the Lunaracer 2. It feels like rubber and doesn't breathe. I wish the Lunaracer had a lower heel drop too, but right now if I had to choose my marathon racer, I'd probably go with the Lunaracer 2. (Lunaracer 1 (or 3) is much too narrow for

Comments: First of all, very nice looking shoe.  Not everyone likes crazy colors, and this is a throwback to the classics.  Now for the actual fit; I'm a 5ft, 10in/142lbs/male with flat feet.  The middle and heel fit snug as a racing flat should but the forefoot was quite roomy.  I offset this with slightly thicker socks.  Ran a 5k race in these and although the shoes give a lot of support I wish they were a tad lighter.  All in all a good shoe, but could be more narrow in the forefoot and is made to cater to 10k to marathon distances.
From: TJ, Davis, CA, USA

Comments: I have been running in the Asics Hyperspeed for the last year. That includes everything from running Marathons to training in them. I usually get about 300 Miles out of them before they are trashed. They are simple the most comfortable shoe out there. I rotate these with the Nike Free 3 and the Tarthers, another great training shoe. I am 56 and have no issues with these shoes. These are like the shoes I ran in during the 70's. Awesome shoe!
From: Steve, Leomnster, MA

Comments: Love this sneaker.  Have raced half-marathons in them and they hold up great.  I burn through them pretty fast though, probably every 2 1/2 months vs. 3-4 in other sneakers, but it's a more minimal shoe and it's priced less as well.  I do think I need a little more cushion for the marathon.  I've started noticing aches and pains in my feet that I never had before, so I switched to a sneaker with a little more cushion and the issues went away.   I'll keep the Hyper Speed for training under 10 miles and races under half-marathon.

Comments: I've run four pairs of these into the ground, about 450 miles on each. I use them from 5K to Half Marathon races. I put up to 17 mile long runs in them as well.
From: Freddie, Bakersfield, CA, USA

Comments: Excellent. Wore into the white foam after about 250 miles mostly on pavement.
From: Andrew N., OKC, OK, USA

Comments: This is the best shoe I've ever run in, and tried about different 6 pairs of various brands over the past 2.5 years. I just wore through my second pair of Hyperspeeds. I use it for daily training as well as racing anything from a 5k to an ironman marathon. It's light, yet stable and very responsive. And for the price...what more could anyone ask for?? My solitary complaint is that mine have worn quickly. I put a lot of pavement miles on them, so after ~250 the soles are worn through to the white foam. I like to get ~800+miles out of a pair of running shoes before they are trash. A more durable layer on the bottom would be nice.
From: Peter, Philadelphia, PA, USA

Comments: I am a racewalker.  This is a very comfortable shoe.  I use it mainly for my distance runs, but I have also used it for interval work on the track.  The sole wears very well.  The only issue i have with sole wear is the toe on my right foot wears faster than the rest of the shoe.  This happens with all of my shoes.  This shoe feels great on my feet.
From: Alfred, Birmingham, Alabama

Comments: I am now on my 6th pair of the Hyperspeed-4's. I have found them to be a good minimalist shoe, and I use them for virtually all training.  I have used them for 5Ks and Half-Marathons. I like the very light weight, the low price, and the ingenious design of the sole.
From: Michael, Fort Wayne, IN, USA

Comments: An odd shoe, insofar as it exists between what I'd consider a true racing flat and the lightweight trainer category. It has too much heel lift to belong to the former; yet it is much to light, flexible, and generally lacking in stuff to be the latter. As such, I could never find a perfect use for it. It's good for speed work and short races; but something lower is better. I wouldn't run anything longer than a 10k in it again; there simply isn't enough cushion. Still, it's a good shoe, and a good value, so long as you know what you're getting
From: Alex, Lawrence, KS, USA

Comments: I'm a stocky 5'4" 160 lb male runner with bowed legs and flat feet who spends a lot of money experimenting with shoes. I used to do all my road running in Asics 2100 series. After experimenting with minimalist trail shoes for my trail running I started transitioning to a more forefoot style of running. I began to use light weight trainers for the road to experience that same feel for the ground feeling I had on the trails but they just didn't do it. Finally, I went pretty minimal with the adizero pro and loved them but for shorter distances. I stumbled across this shoe and gave it a try. WOW!!! I ran 4 miles in them right out of the box and I ran 5 two days later. This is the most comfortable and versatile shoe for forefoot/midfoot running on pavement. They have a softer outsole than a traditional racing flat making it great for everyday training yet they are as light as most racing flats. I would say they fall somewhere between a racing flat and lightweight trainer as far as protection and feel. Like the adizero pro, it's really the minimal heel to toe ratio that sets them apart from other shoes. I've reasearched them all and Asics has a one of a kind in this shoe. It is simply the BEST shoe I have found for the road for my newly found running form. Hope to see this one around for a long time and it would be even nicer to see it in black.

Comments: Love this shoe for speed work, great for 5 and 10Ks but not enough there for the 1/2 marathon.
From: Kristin, San Diego, CA, USA

Comments: This is a nice road racing shoe/light trainer.  If you are an asics fan, you will not be disappointed.  I have worn it in both 5 and 10k races with positive results.  I am not sure that I would use it in anything longer, though.
From: Jeff, West Chester, PA, USA

Comments: Runs large. I wear a size 10.5 in adidas or Saucony. A size 10 Gel Hyper fits correctly. Good minimalist shoe.
From: Neal, Lexington Park, MD, USA

Comments:  I love this shoe i ran a 10 mile race in this shoe and i did it in  51 minutes.
From: Greg, Seattle, WA, USA

Comments: Turns out the Hyper Speed isn't quite enough shoe for me.  For forefoot/midfoot strikers and/or lighter fast-paced
runners, it would be great. Fortunately, the Tarther is enough shoe for me while still being plenty responsive.
From: Anonymous

Comments: Great shoe!  Runs more like a lightweight trainer than a pure racing flat.  The Speedstar was my training shoe, but, the latest version (4) is too soft for me.  The Hyper Speed has just enough cushion to crank out miles.  Plus, it's wide enough to be comfortable for daily use.  Although I'm annoyed that Asics keeps making their neutral shoes more stable with various types of lateral crash pads, at least they make some great lightweight and truly neutral shoes.  A true supinator will be best served by the Hyper Speed, Tarther or even Piranha.
