Comments: I bought these from Running Warehouse with the mind of using them mainly for racing and speed training. However, after my first run I am convinced that these shoes can be used for all kinds of training, walking, and casual purposes. These shoes are one of the best shoes Asics has ever made. Although they are advertised, marketed, and designed to be minimalist racing flats, they also have the cushioning that feels like more advanced shoes like the GT-2000. The support on these shoes are also surprisingly sufficient. If your feet pronate without the needs to wear motion control shoes, these may be adequate for your needs, without having to wear clunkers like the Kayanos. The most amazing thing about these shoes isn't the lack of compromise between it's weight-support-cushioning ratio. Rather, the most amazing attribute of these shoes is how responsive they are. The trusstic system makes these shoes bounce back on each stride, making them feel super quick without over exerting your precious energy. The DUO Density foam will also allow these shoes to last a lot longer than many supportive shoes without this feature. I have minimal supportive shoes that had its midsoles compress prematurely due to slight pronation during the end of my long distance runs. What I find conflicting between my personal experience and online reviews is that these shoes are not as narrow as what I read online. However, use the shoe fitr function on this site to have an idea of what size you should purchase. I have yet to use my trusty insoles in the DS Racer 9, but test fitting my insoles make these shoes even more comfortable and better fitting. Out of the box, these shoes are already amazing if you typically don't use insoles. In conclusion, these shoes are greatly underpriced for what you get.

Comments: The best update to the DS Racer series since the ruby red DSR VII. These shoes are very light weight, offer a well cushioned and supportive ride (due to the structured upper and firm heel counter). The DS Racer 9 is the jack knife of running shoes and is versatile enough to tackle any race up to a Half Marathon. I set PRs in every race this year including a 16:19 5k and a 1:15 HM while racing in this flashy kicks. The fit in the toe box is tighter and I suggest using the ShoeFitr to dial in the correct size. This is THE racing flat for runners/triathletes training in traditional, supportive trainers (ASICS 2000 series/ Brooks GTS) who want to experience speed!

Comments: Go half size to one size up. Very tight toe box compared to the noosa tri 7's.

Comments: This racing flat is a fast one. Certain flats just feel fast. I had the Gel Bandito, and this is a much better shoe. The ride in the DS 9 is similar to the Saucony Fastwitch 4 (btw the 4 is competely different than the Fastwitch 5), but the DS 9 is more durable. As far as sizing, I wear a size 12 except for some Nike's like the Structure Triax 11 through 14 (sz. 12.5) I have a slender heel and a wider forefoot, C/D width. I ordered a 12 in DS Racer, and they are the good snug that a flat should be. These are tight in the heels. My only word of caution is that I don't think these would work for me in anything over a 10k. The forefoot doesn't provide enough protection for me. I am 6'3", 185#, body fat 8-10%(6:15 pace 5k, 6:45 pace Half). For the longer races, I use the Brooks ST Racer 5. They don't feel as fast, but they have a little more cushioning in the forefoot and more support overall. The open forefoot does retain small rocks, seeds, etc. I would recommend the DS Racer 5 for 5k and 10k races. Lighter runners may be able to runner Half and Full marathons in these.

Comments: This shoe was a terrific purchase for me. I'm a 140lbs Masters runner, 40+ miles/wk and ~6:30/mi half marathon pace. The DS Racer 9 provides excellent feel of the road without beating me up. I use the shoe as a racing flat. Since I wear very rigid orthotics I have been hesitant to buy any kind of 'racing' shoe in the past. My previous racing shoe was the Mizuno Wave Elixer 5. They always felt klunky. The light feel of the Racer seems to make a real performance difference. I should have switched to the DS Racer sooner. I have a thin frame and feet. Others have complained about a cramped toe box in the DS Racer 9, but it is perfect for me even with the orthotics. My normal street shoe size is 10, and 10.5 for running shoes. Based on other comments I ordered an 11 in the DS Racer 9, and that was the right choice.

Comments: I switched to the DS Racer 9 for a marathon after several pairs of DS Trainers, prior to significant changes in the latter. I tried several different racing shoes (Saucony Fastwitch, Brook Racer ST) and chose the DS Racer for the firmer sole, relatively more support, and great power that I got in each turnover. I'm on the larger side for racing shoes (6'3", 175 lbs), but the DS Racer was firm enough for me. I ran a PR and my feet and joints felt better than I recall with other shoes. As with others, I found the DS Racers to be snug throughout, particularly in the toes, and I felt that the upper lace holes could be placed better.

Comments: I attempted running in 0-6mm drop shoes for about a year before I finally gave in and found these. I had dealt with achilles tendonitis, soleus pain, and medial shin splints before. I must say that these shoes are near perfect for someone needing lightweight support. They feel fabulous on a run, just enough support to allow the calves to relax and move the heavy lifting of shock absorption and power generation to the hips where it belongs. The forefoot is soft, flexible, and relatively thin. This flexibility allows natural pronation when landing midfoot instead of the loud slapping of a stiffer sole. The softness allows you to feel some texture under the forefoot. Rocks, branches, cracks in the sidewalk, are not at all painful, but not numbed down to no longer exist either. The 10mm heel is just low enough to allow for a midfoot strike, but is well cushioned for a heel strike when going down hills. If you don‚t like the drainage holes underneath, they can be easily plugged with a small dab of epoxy or rubber cement. They are recessed enough so that such an operation would have no effect on the underfoot feel.

Comments: Not sure if its my training or these shoes or both but I was running like a cheetah with them
on. LIght with enough support, these shoes have made a huge impact on my PR. I ran my fastest triathlon sprint, olympic, and half ironman this year. Still wondering if I should try a full marathon or stick to my extra support asics kayano. I hope next year's model will be just as great with more colors to choose from.

Comments: Holy Cow! The second I put these awesome shoes on, I knew right off the bat I was going to be super fast or at least improve on previous run. Sure enough on race day, of course with my regular work outs, these shoes out perform and exceeded my expectations. I was jamming like a cheetah. I own several pairs of stability shoes for difference purpose. On race day this is my go to shoes. I highly recommend but wish there was more color to choose from.

Comments: The Gel DS Racer 9 is so snug that I wear a full size up in this shoes, incredible! I normally
wear a size 9 and I had to buy a size 10.
From: Joe, USA
Comments: Nice shoe, for me the DS 8 was too loose in the forefoot. I have run a 6 miler and a 20 miler in them. The DS 9 provides plenty of cushion for the long run and just enough support when you need it towards the end of the long run. Heel to toe transition is smooth as silk.
From: Don, WI, USA
Comments: I would say the short runs more short than tight in the forefoot but either way I had to go up a half size which I have not had to in asics in 20 years of running in them. The shape/fit of the shoe (even with the short fit) seems to mimic that of the ds trainer X, which was the best shoe ever. Will buy it again a bigger size and then review the performance.
From: Jane, Boston, MA, USA
Comments: These shoes are narrow in the forefoot. Gone is the comfortable fit of the DS Racer 8. My toes feel like they are being shoved into pointed shoes. Very unfortunate because they do look nice and feel like they have more support in the heel.
