Twenty years of Nimbus! We end the last month of 2017 with a new running shoe from ASICS: the 20th version of the GEL-Nimbus.

With a new round of colors and updated running shoe specs, these kicks are a holiday gift to the neutral runner.

The ASICS GEL-Nimbus 20 is lighter, sleeker and faster than ever before. With updates to the upper and heel collar, the GEL-Nimbus 20 offers a broader fit and the true-to-size feel that you expect from ASICS. Flytefoam, Super SpEVA, and GEL provide comfortable and responsive cushioning for neutral runners looking to log lots of miles.

"We opened the upper a lot more with the mesh design on the Nimbus 20. It's going to accommodate a broader fit... more open around the lateral and the medial side of the toe box. The mesh construction is also going to be a little bit lighter," says ASICS rep Greg Grevin.

Nope! Stayed the same. Flytefoam on the bottom and Super SpEVA on the top and filled with that gel you've always loved. Durable AHAR in the heel and the soft, squishy DuraSponge in the forefoot.

The heel collar has been modified for a snugger, more comfortable fit, and ASICS improved the heel counter, designing it to be more flexible and softer.

It weighs in at 10.7 ounces for men and 8.8 ounces for women with a 13mm offset for women and 10mm for men.

For ladies, you still get the women-specific cushioning you know and love from ASICS. The soft top layer of SpEVA is still there.

You can also look forward to the Guidance Line that ASICS has had before for stride repetition and to glide the foot cleanly forward. The trusty Trusstic System is still going to be there to stabilize your foot.

"The Nimbus is still that high-end, cushioned shoe that you've loved for years and years, so if you neutral runners are looking to log a lot of miles, this is a great choice for you."

Who knew safety could be so fashionable? If you're on a road that traveled by the public, it's especially important that you wear gear to enhance your visibility to travelers. The important part is to make sure you're being safe. You want to take the appropriate precautions and wear bright reflective running gear so you're seen! Here is a list of the best reflective running shoes that 2017 has to offer.

Now showing off an entire spectrum of colorful reflectivity, the new ASICS Lite-Show collection features the GEL-Kayano 24, GT-2000 5, GEL-Nimbus 19 and reflective clothing to match.

This year, ASICS introduces their brand new GEL-Kayano 24 to take over for their previous installment. Over the years this shoe has gained a reputation of being a cushioned and responsive workhorse.

The GEL-Kayano 24 is designed with comfort and versatile stability in mind as it can be worn by neutral runners and moderate overpronators, too. This time around, ASICS has changed the upper in a way that feels more forgiving and therefore, more comfortable.

This shoe offers overpronators stability and comfort to improve running efficiency and decrease the risk of injury over varying distances. And as mentioned, while it's perfect for the overpronator whose predisposed to an inward rolling motion as the foot progress toward toe-off, it will also work for neutral runners.

Our in-house product expert, Cathy, said that "after having the chance to try these premium running shoes, I found that this iteration is probably my favorite. This is simply based on the improved fit of the shoe."

As an American Podiatric Medical Association doctor approved shoe, the Kayano 24 as compared to the Kayano 23, has new jacquard mesh, meta-heel clutch design to hold the heel in place, and a lower collar (so no friction occurs on the back/sides of the ankles).

"I’ve always loved the ultra-cushy feel of the Kayano and I felt that it performed so well for me in it’s excellent, shock-absorbing ability. The only complaint that I had about previous models were the narrow and constrictive feels I got around my forefoot from the upper. But the new jacquard mesh material and its construction in the GEL-Kayano 24 provides a more accommodating fit," Cathy comments.

The 24s incorporate ASICS' Impact Guidance System, FlyteFoam, FluidRide, FluidFit, Heel Clutching System, Dynamic DuoMax, Guidance Line, Guidance Trusstic System, SpEVA 45 and Plus 3 (only in women's version) Midsole technologies.

The Plus 3 midsole tech is ASICS women-specific cushioning, 13mm drop for women, compared to a 10mm drop for men.

"For lovers of this stability staple by ASICS, you’ll get all that soft and pillowy good stuff you’ve gotten before, but if your piggies need room, this shoe has that, too! With the plethora of new colors, you’ll be sure to find one (or more) that you just can’t live without." To watch an overview with an ASICS representative, watch the video below.

"Tennis is a game of give and take. You can run around your backhand to hit a forehand, but in doing so, you'll open up the court for your opponent's reply. Tennis gear also requires players to strike a balance in order to find the best fit for their games."

Not many stability shoes feature an internal bootie, but Yonex's update to the Power Cushion Eclipsion does, along with a superb level of underfoot cushioning. It makes for an unparalleled combination. The redesigned fit now allows for more extension in the forefoot, while keeping the midfoot and heel better protected. The shoe starts firm, but flexes adequately over time and "plays lighter than its static weight" due to the overall comfort, according to one tester.

ASICS Loyalists: Some of you may have pondered what happened to the 2100 series. Fear not; your go-to shoe now goes by a different name: ASICS overhauled one of the most popular shoes in the market to redefine stability as we know it. Such modifications may cause some uneasiness among the 2100 series aficionados, but, in this case, we at Holabird Sports think change is good.

GT-2170 vs. GT-2000: What has changed? If you're looking for a soft, cushioned ride, look no further. ASICS has truly outdone themselves in producing a plush, gel feel in the GT-2000. With larger gel units in the forefoot and heel, this model will leave you feeling oh-so-comfortable for the duration of your run or workout. ASICS has added a second layer of SoLyte foam to the top of the midsole, providing better cushioning and shock absorption just beneath the sock liner. Keeping both genders in mind, the GT-2000 has implemented a softer layer for women and a firmer one for men. With ASICS' patented Personalized Heel Fit (PHF), two layers of memory foam in the heel will mold to your fit, creating a superior fit that lasts.

But is it still just as supportive? Will you be able to safely transition from other stability shoes to the? Yes and yes. ASICS has replaced the old Duomax medial posting with the new and improved Dynamic Duomax, allowing for a smoother control of overpronation. Compared to the GT-2170, the medial support is less aggressive in the GT-2000 without compromising support and functionality. Additionally, the Guidance Line in the outsole encourages a firm foot strike and a steady toe-off.

Increased cushioning and new a medial post must mean a heavier shoe, right? Not at all. In fact, the GT-2000 is even lighter than its predecessor. I weighed the women's model in at 9.3 ounces, .6 ounces lighter than the GT-2170. The men's version slimmed down to 11.3 ounces, shaving .2 ounces from the previous model. With thinner overlays in the forefoot, the GT-2000 is not only lighter, but also more flexible.

My thoughts: Shin splints begone! When I first stepped foot in the shoe, I noticed how plush it really is. Consider it a featherbed for your foot. Already appreciated for a soft, gel-cushioned experience, ASICS has proven that stability shoes can have same soft ride as many neutral shoes. I loved the improvements to the medial posting. The Dynamic Duomax is gentler than the old Duomax, but is still equally supportive. I didn't notice any distinct rigidity beneath the arch and heel, but still felt the necessary correction we would expect from a stability model. For stability shoe gurus, it may have seemed strange that the GT-2000 did not have a painted posting. Resembling more of a neutral shoe in fashion, ASICS has done away with the classic grey-on-white look in the midsole. I noticed a slightly narrower toe box, but my feet still had plenty of room to breathe. The arch ramp didn't seem quite as prominent as it did in the GT-2170, but still felt comfortably supportive.

The Bottom Line: The GT-2000 is the perfect shoe from a workout on the elliptical trainer to a 20-mile long run. ASICS has produced a great blend of cushioning and functionality in this model, and it is built to last.
