The standard (medium) width for women is B, while the standard width for men is D. Shoe boxes and labels will only identify widths other than standard. Within the shoes, wide and narrow widths are identified on the label, underneath the tongue — ie. T005N(2E).

When is additional width needed?
Visible stretching or bulging on the outsides of forefoot materials is a good indicator that additional width may be needed. These sizes are available in many of our Running and Training shoes. In some cases, men can wear women’s styles to achieve a narrow fit and women can wear men’s to get a wide. If this is needed, please use the references above to determine comparable size lengths. Please note that the differences of width between narrow, standard, wide, and extra wide are usually only a couple millimeters and are proportional to the size of the shoe. Most additional width will be found in the forefoot.

Longitudinal groove that decouples tooling along the line of progression for enhanced gait efficiency.

Guidance Trusstic™ System Technology

Heel Clutching System™ Technology

I.G.S® Technology (Running)

ASICS® design philosophy that employs linked componentry to enhance the foot's natural gait from heel strike to toe-off.

Rearfoot and Forefoot GEL® Cushioning Systems

Attenuates shock during impact and toe-off phases, and allows movement in multiple planes as the foot transitions through the gait cycle.

Seamless Construction

The use of seamless materials reduces the potential for irritation and friction caused by traditional stitches and seams.


Severe Over
Pronation is how a runner's foot rolls medially between footfall and toe-off. Underpronation is when the foot rolls outwards, overpronation is when it rolls inwards, and a neutral pattern is when little rolling occurs.

Matching a shoe's properties with the runner's running style will increase comfort, running efficiency, and contribute to decreasing the risk of injury.

Rated 2 out of 5 by from Weird Fit I usually wear Asics in a size 9, but ordered these in a 9.5 due to the many reviews mentioning how short the Nimbus 19 runs. The shoe was initially very comfortable right out of the box (I have narrow feet so a lot of shoes are too wide), but my toes started to go numb after walking around for a few minutes. I exchanged for a size 10. That pair fit well in the toe, but the rest of the shoe was way too wide for me. I ended up sending the shoes back for good. Bottom line: The fit is short, narrow, and just kind of weird. I did give 2 stars because the cushioning is really nice and I like the way the shoes look.

Rated 1 out of 5 by from Disappointed I have a few colors in the Nimbus 18 and I loved them and still do. I bought the 19's since I was ready for a new pair but like everyone else they were so tight I went another half size up and they just don't have the comfort the 18's do. They hurt the ball of my foot so definitely not same comfort as the 18's. Sometimes i suffer from plantar fasciitis and The heel to toe mm has changed, I'm not sure if that has something to do with it but they don't feel anything like the 18's and sadly,I had to buy another pair of the 18's.

Rated 5 out of 5 by from Gel-Nimbus 19: The Best Running Shoe The Gel-Nimbus 19 Asics running shoes are a great choice for long-distance runners who desire a quality shoe. I bought these a little over a year ago, and they have worked well for me so far. I run anywhere from 5 to 25 miles in them per week. I also ran a half marathon in them, which is 13.1 miles in one race. I have always chosen Asics shoes for my running needs and have not regretted this yet. I believe these shoes would be a great fit for all of you as well. The criteria I will be using to evaluate the Gel-Nimbus 19s are: comfort/support, style, and breathability/flexibility. Comfort/Support: The gel cushioning system provides both comfort and support for runners. I am normally very blister-prone when running but the Gel-Nimbus 19 model has not caused any blisters or friction, due to its seamless materials. Along with this benefit, the height of the soles on these shoes helps to prevent pain in the arches for those of you who experience arch pain easily. I personally tend to experience arch pain when my shoes are worn out, but this model has been successful in keeping this pain away for over a year now. Style: The Gel-Nimbus19s come in different color schemes, depending on your preference. This model is especially nice for those of you who consider style an important factor when choosing your running shoes. Asics can sometimes be known for their less stylish shoes, as a cost for comfort. However, this model provides plenty of style. Some of you may hesitate purchasing these shoes when looking at the price tag, but the overall quality and style of them make it very much worth it. Breathability/Flexibility: Another major benefit to consider when making your decision would be the breathability and flexibility of this model. When running for long distances, your feet may get a bit sweaty, but that’s nothing to worry about with the Gel-Nimbus 19s. The material is excellent at providing moisture management. Additionally, the laces on this shoe are very flexible and can be adjusted quite tightly for those of you who prefer them that way. I personally prefer a bit loser laces otherwise my feet fall asleep. If this is how you are, these shoes are the ones for you as well! Overall, I am very pleased with the Gel-Nimbus 19 Asics shoes, and I have confidence you all will be satisfied too. I hope this review was helpful. Let me know if I can answer any other questions. Happy running!

Rated 1 out of 5 by from Too tight Been wearing nimbus for many many years, this new awful, way too tight, less cushion. Very disappointed in the show

Rated 1 out of 5 by from I'm Super Disappointed I've been running in Asics for over twenty years, and within the past year, I've had some serious issues with their shoes. They don't fit like they used to. I have always worn a size 7, and now it's too small. The size 7.5 is too big, and it's as if they've changed their sizing ever so slightly. Have you changed your sizing? Something is off, so I know a change has been made to something.

Rated 5 out of 5 by from Love the FlyteFoam The new foam in the shoe greatly reduced the weight from the 18s. But with new shoes, I know to always air on the side of caution, because added cushion can move the foot forward, so they can run a little small- and they run about half a size small. Love these and can wait to put some more miles in them.

Rated 1 out of 5 by from Much smaller Every year I have to get a different Nimbus size. There doesn't seem to be much consistency in sizes from year to year. These were way to small in the toe box and actually pushed on my big toe bone on the top. I'll go with a bigger size and see if I'm more impressed but as of now, I did not care for the 19's at all and have been wearing these since the 14's.
