The Best Road Running Shoes of 2021

Brooks is back with its famous lightweight trainer, now available for the first time in GTS (stability version). The all-new Launch 8 is already creating a buzz in the running world and is noticeable a mile away! Available in lime green and a dusty rose hue, the benefits of the Launch 8 transcend outward appearance—this trainer performs. Whether opting for Brooks' Go-to-Support technology or the standard 8, here's what you should know to decide on using the Launch for your daily workouts.

Like some of its colleagues (we're looking at you, Glycerin 19), the Launch 8 comes in both neutral and GTS. GTS provides added support on the shoe's platform with GuideRails technology and works to stabilize a runner's stride. Unlike previous models that have offered GTS, the Launch 8 incorporates GuideRails technology seamlessly into the shoe's design. The overall feel is a firm, somewhat dense ride that gets the job done. The standard 8, meanwhile, lends itself to as smooth of a ride as its GTS cousin. The two share many similarities; both are leaning toward a more responsive feel and an uptempo pace. This responsiveness comes from the midsole, engineered with BioMoGo foam, though some runners were less than impressed. One comment focused on the overall stiffness of the shoe, even after a generous break-in period. BioMoGo also lacks pop, making it fairly unremarkable compared to the Brooks Tempo or Elite models' technology.

Also, the upper of the Launch 8 is designed with an air mesh to keep feet cooler. It's worth noting that, with a few exceptions, nearly all trainers have a breathable mesh upper—it pretty much comes with the territory. The toe box is roomy and keeps feet locked in place throughout a run. The outsole is excellent on both the standard and GTS versions, with blown rubber that lasts after miles of use. The overall traction and durability are unparalleled for the caliber and price point of the 8.

In summary, the Launch 8 is ideal for uptempo runners and those seeking a highly durable shoe. Despite some reported stiffness, users didn't have many other complaints; however, the midsole wasn't unanimously successful. Despite its lightweight design, BioMoGo was simply too firm for a comfortable ride. These are also not recommended for runners who expect a snap or "pep" in their step to propel them forward. For an extremely affordable price, given the great Brooks name and the shoe's quality, the Launch 8 delivers. However, if you are expecting something groundbreaking or truly remarkable, you would do well to look elsewhere.

The Asics Gel Nimbus 23 represents the old guard of the Japanese brand. As such, it offers a classic but very reliable configuration. Does it make sense to go on with the Nimbus, or is it time to ditch it for sleeker models?

First of all, Asics has made few changes to its bestseller. The Nimbus 23 retains the very successful upper from the 22 version with a few improvements, such as a thicker, more comfortable tongue to lock-in the foot. The lockdown is comfortable and can be forgotten, which in the end is the most important thing. The toe box has a moderate size and should fit most runners.

Cushioning provides an unvarnished but very satisfying ride for daily training and long distances. The combination of foam and Gel pads gives good shock dispersion. The underfoot feel is relatively soft with a touch of firmness. An interesting point unanimously noted by the testers is the platform's flexibility, especially thanks to the deep flex grooves. The shoe offers a slight rebound but nothing spectacular. Finally, let's note that although the Nimbus is a neutral running shoe, it slightly stabilizes the foot's movement, which can reassure runners who like to have some structure in their shoes.

The outsole is based on previous models' winning formula (also present on many of the brand's models): AHAR+ under the heel and AHAR under the forefoot. This carbon rubber is undoubtedly one of the elements that contribute to the shoe's high weight (309 g/10.9 oz), but it has the advantage of making the shoe very durable for long workouts.

In summary, the Asics Gel Nimbus 23 remains true to itself with a traditional, tried-and-tested configuration. It's an interesting choice to have in rotation with other lighter and snappier models. However, all truth be told, if you've never worn a Nimbus in your life, there's little reason to start.

Every year, the Adidas UltraBoost is much anticipated but eventually leads to plenty of mixed reviews. The UB21 is no exception and proposes the same formula: a model halfway between a sneaker and a running shoe that tries to combine style and performance.

The sleek design is an achievement on its own and will please runners who like good-looking shoes on their feet. The Primeknit upper and its bootie conception offer great comfort and impeccable foot lockdown, according to the testers. It's both breathable and stretchy for a precise and adaptive fit. Also, the Primeblue material uses 50% of recycled plastic from the oceans. The UB21 also marks the midfoot plastic cage's return that many runners decried in the past on previous versions. However, luckily it's barely noticeable this time.

Then, the cushioning shifts gear with a heel stack height of 31 mm instead of 27 mm the year before. Adidas announces 6% more Boost, and it shows: the small white TPU granules give a massive sole, especially in the heel area. Another significant change, the Linear Energy Push plastic plate, replaces the Torsion System of the previous models. It gives structure to the platform for better stability and a snappier toe-off. However, in practice, testers found the cushioning to be firm and clunky, with little bounce, although the shoe does provide a stable ride. The weight doesn't help with 12.3 oz (348 g) (even more than the previous model), limiting its speed ambitions.

Finally, the outsole also boasts a new design and succumbs to the exposed foam trend (only in the center) without limiting durability or grip, both of which are very good.

In summary, unless you're a fan of the UltraBoost collection, there's little reason to opt for the UB21 other than its comfortable lockdown, good shock absorption, and sleek design. Otherwise, the Ultraboost is too heavy and too stiff for an enjoyable ride, even for daily runs.
