ASICS GT-2000 12 Review (2023)


ASICS GT-2000 12: Consistently Improving
By Matthew Klein

The ASICS GT-2000 series has been a quite staple among runners wanting a moderate stability daily training shoe. The last several versions have seen some major changes, which is odd coming from a company that used to be so consistent and boring. ASICS has been anything but boring recently as the company has made huge strides in performance, stability and comfort. The ASICS GT-2000 12 sees further changes in all of these areas with a design that looks to be inspired by the Kayano and Kayano Lite series. A wider base, sidewalls, internal stable geometry, upgraded foam and more moves the GT-2000 series forward as a moderate stability daily training shoe that remains relevant in today's footwear landscape.

RUNNING SHOE SUMMARY

The ASICS GT-2000 12 is a moderate stability daily training shoe for those who want a sturdy but lighter ride and a secure performance-edged upper. The new FF Blast Plus midsole makes for a lighter and bouncier ride. The improved heel bevel and PureGEL add to the smoothest transition at the rear this series has ever seen. The combination of factors, including the internal 3D Guidance System, continue to provide moderate unobtrusive medial stability along the length of the shoe. The updated Jacquard mesh up top makes for a comfortable, secure and slightly snug fit that adapts to the foot. Every part of this shoe improves from the previous version, continuing the tradition of the GT-2000 12 being a reliable, comfortable moderate stability daily training shoe for easy, long, and uptempo mileage.

FIT


The ASICS GT-2000 12 fits me true to size in my normal men's US size 10. The fit is slightly snug through with an almost performance-like feel. The forefoot fits snugly and is tapered. The Jacquard mesh does stretch to create mild secure compression. The midfoot is also slightly snug with a thin gusseted tongue. I did not have to tighten the laces at all to get a secure fit. The heel fits snug with a moderate amount of heel collar cushioning and a stiff counter. I have not noticed the counter due to the well-placed heel collar cushioning but those that are sensitive should approach with caution. The security is excellent and I have not had to lace lock the shoe at all. The slightly snug fit will work best for those with normal or narrow-width feet. For those that want more width, there is a WIDE version. The inner liner is comfortable and can handle sockless wear. I found this opens up the shoe a little for those who find it restrictive. However, I elected to wear socks given the recent heat (SoCal Summer) has made my feet sweat as the upper is a little warm.



PERFORMANCE

The ASICS GT-2000 12 continues as a moderately cushioned daily training shoe. The stack height has increased to 32.5 mm / 24.5 mm  (31 mm / 23 mm of version 11). There is an 8mm drop and the shoe feels as such. The midsole now features full-length Flytefoam Blast Plus with PureGEL in the heel. This makes for a cushioned ride up front that has some bounce to it throughout the length of the shoe. The weight has dropped further from the last version to 9.5 oz. Combined with the new midsole bounce, the GT-2000 12 feels lighter even than its listed weight. It still has enough there to feel like a training shoe but it is light enough that it gets out of the way while running. I have used this shoe for long runs, easy runs and a fartlek. The relatively lighter weight and bouncier ride work well for uptempo work, making it a great option for both newer runners experimenting with different paces and experienced runners who want something on the lighter end of the stability shoe market.

The transitions of the GT-2000 12 are far better than previous ones. The heel now features a posterior lateral bevel and a geometry that compresses well. This finally makes for a smooth, non-clunky heel transition. The midfoot is fairly nondescript while the forefoot has normal/moderate flexibility. The front of the shoe has a moderate forefoot rocker and mild toe spring. The transition off the front of the shoe feels smooth and easy.

Durability wise the GT 2000 12 has been great. I have 30 miles on my pair with no major wear on the outsole even in my usual spot (posterior lateral heel). I recently hit 100 miles on my pair of Kayano 30s and given the similar outsole setup and initial wear I would expect a high number of miles out of the GT 2000 12. Surface wise the GT 2000 12 does best on dry road and mild dirt. It was raining heavily in SoCal recently and I found the outsole to have only average traction on wet pavement. The outsole can handle mild trail but is certainly not a technical trail shoe. This is a moderate stability daily training road shoe.

"This is a fantastic update that is not only my favorite of the series, but may be my favorite stability shoe of 2023."



STABILITY

The ASICS GT-2000 12 is a moderate stability that utilizes newer concepts/ideas. There are medial and lateral sidewalls in the lateral heel and medial heel/midfoot. There are small sidewalls on both sides at the forefoot, centering the front of the foot quite well and subtly. The sole is wider with a filled-in midfoot. There is plenty of sole flare in the forefoot and heel. The heel flare is offset by a solid posterior lateral heel bevel and compressive geometry on the lateral side. Finally, the 3D Guidance System inside the midsole provides geometric medial stability. The foam provides more medial resistance the harder you collapse in and gets out of the way when you don't. The stability is not in your face but well-integrated into the sole and feels quite good.

The GT-2000 12 will provide plenty of medial stability for those with mild-to-moderate stability needs throughout the length of the shoe. Those who want a post-like feeling will need to approach this shoe with openness as it doesn't have the most direct feeling initially but will provide plenty of support while moving.

Editor's Note: What is the 3D Guidance System? ASICS describes it as a combination of the wider base, stable geometry, and supportive upper.




Thoughts as a DPT: Progression in Stability Concepts
By Matthew Klein

The ASICS GT-2000 12 is the first of the series to move away from some kind of medial post or trusstic system. ASICS has taken huge efforts to progress forward in thinking about stability differently, as evidenced by the fact that medial posts are now rare within their line. Instead, we see their stability shoes (and many of their stable neutral shoes) with wide bases, filled-in midfoot regions, sidewalls and something called 3D Guidance systems. The 3D Guidance system is a fancy way of saying they have set up the internal structure of the midsole to keep the foot centered as needed. This essentially means that the shoe adapts to the unique mechanics of the runner, gently providing more resistance in response to more force placed in certain areas. The more stability you need, the more you may feel the medial side. The less, the more this disappears. 

This concept is key to what we and others have been talking about for years. Not everyone needs a super stiff motion control shoe all the time. We know that people move differently and need different things, even as they progress through a run. We also know that people's gait patterns are as unique as their fingerprints and despite their variability can have a unique pathway/signature (Nigg et al., 2017)). So how do you design a shoe that can adjust to all that variation between and within individuals while still providing stability? That is where all these newer concepts, including sidewalls, sole flaring and more have come in. The goal of a good stability shoe should be to provide stability where/when you need it and get out of the way where/when you don't. This is extremely hard to do and we at Doctors of Running applaud the companies trying to execute this.

The GT-2000 12 and its internal geometric stability (like the recent Kayano and Kayano Lite) are a great step in the right direction. The more you compress the foam, the more you get into firmer elements that try to keep you centered. The elements are not there to completely stop motion (we know that doesn't usually work) but instead guide you forward. This is set along the length of the medial side rather than in a single spot (heel, midfoot, forefoot) to ensure the shoe works for a larger variety of people. We know people move differently and we also know people move differently at different times. Thus, adaptive stability, like the internal geometry of this shoe, is key to making better footwear that works with a variety of runners and not against them.

RECOMMENDATIONS

Everything I recommended about the sole of version 11 was accomplished in version 12. There is a far better heel bevel, there are additional geometric aspects that also allows appropriate compression at the posterior lateral side and the bevel is facing more posterior lateral without being extreme. The shoe is lighter with a bouncier foam that provides a smooth ride that you can forget about while focusing on your run. My only continued recommendation is the toe box. It is still a bit tapered, although the mesh does stretch. I would like to see the forefoot be a little more rounded for appropriate toe room. This does not have to be clown-like, but a little more room can help the forefoot gently spread and facilitate appropriate forefoot transverse plane movement for shock absorption. Outside of that, this is a fantastic update that is not only my favorite of the series, but may be my favorite stability shoe of 2023. 

WHO THIS SHOE IS FOR


The ASICS GT-2000 12 continues its place as a stand-out daily trainer for those that need mild to moderate stability. The adaptive stability comes from many newer methods, making it a great option for a variety of needs in a variety of areas. The bouncier midsole makes it plenty cushioned while the moderate stack height keeps it pleasantly grounded. The lighter weight continues to allow this shoe to pick up the best but it does best as a consistent pace easy and long run shoe that can eat up miles. The upper continues to be slightly snug with a slight performance fit, making it a great option for those with normal to narrow-width feet. The GT-2000 12 has been a popular model in the past and I see it continuing that trend not only with the stability updates but the additions of a smoother bevel, decreased weight and improved comfort.

I know I have repeated this several times, but the upgrades ASICS has been making to its stability line are impressive. They have completely upended their designs and clearly have found something that works. The similarities between the GT-2000 12 and Kayano 30 are noticeable and I encourage ASICS to continue experimenting with these newer stability concepts. As the company that was once a bit behind, it is nice to see them pull ahead, especially in an important area that has received less attention in recent years.

***Disclaimer: These shoes were provided free of charge in exchange for a review.  We thank the people at ASICS USA for sending us a pair.  This in no way affected the honesty of this review. We systematically put each type of shoe through certain runs prior to review. For trainers and performance trainers, we take them on daily runs, workouts, recovery runs and a long run prior to review (often accumulating anywhere from 20-50 miles in the process). For racing flats we ensure that we have completed intervals, a tempo or steady state run as well as a warm-up and cool down in each pair prior to review. This systematic process is to ensure that we have experience with each shoe in a large variety of conditions to provide expansive and thorough reviews for the public and for companies. Our views are based on our extensive history in the footwear industry and years testing and developing footwear. If you are a footwear rep looking for footwear reviews or consultations on development, we are currently looking to partner with companies to assist, discuss and promote footwear models. Partnership will not affect the honesty of our reviews.
