When every second counts on the trail, Adidas has a new contender that's engineered to fly! The Adidas Agravic Speed Ultra 2 (ASU2) is here to redefine what's possible for serious trail runners aiming for peak performance. This isn't just another shoe; it's the crown jewel of Adidas's Agravic trail collection, meticulously crafted for those who crave blazing speed and unwavering efficiency over vast distances, all without compromising on that crucial comfort, protective feel, or tenacious grip.
But here's where it gets interesting... This latest iteration boasts a refreshingly breathable upper, paired with a boldly curved rocker geometry and a newly formulated, softer Lightstrike Pro midsole. This combination doesn't just feel good; it actively delivers noticeable energy return, practically pushing you forward with every single stride. The result? A shoe that champions forward momentum and truly rewards a confident, efficient gait, especially when the terrain throws its worst at you – think steep inclines, treacherous rocks, or just mile after relentless mile.
A quick heads-up on the fit: Many runners find the ASU2 runs a touch large. This is partly due to a minimalist approach to padding around the collar and a streamlined upper construction. For that perfect, secure race-day fit, we highly recommend trying these on in person before committing.
Let's dive into the nitty-gritty specs:
- Weight: A featherlight 265 grams for men and 230 grams for women.
- Drop: A balanced 8 mm.
- Stack Height: A substantial 44 mm in the heel and 36 mm in the forefoot.
- Lug Depth: 4 mm for optimal traction.
- MSRP: $300.
The Upper: Designed for Airflow and Speed
The ASU2's upper has been completely reimagined to offer a more secure and supportive embrace for your foot, all while ensuring maximum airflow to keep your feet cool and comfortable during those demanding, long-haul efforts. The minimalist collar construction further enhances that feeling of lightness and speed, firmly cementing its identity as a dedicated racing shoe rather than an everyday trail cruiser.
The Midsole: Where the Magic Happens
And this is the part most people miss... The midsole is where the ASU2 truly leaves its predecessor in the dust. The more aggressive rocker geometry works in perfect harmony with the supercritical Lightstrike Pro foam to create a sensation of being propelled forward with every single step. This shoe practically begs you to keep moving, relentlessly pushing you onward. The ride is incredibly energetic and responsive, particularly through the midfoot, making it an absolute dream for sustained, fast-paced efforts.
Now, for a point that might spark some debate: Runners accustomed to more traditional trail shoes might need a little time to adjust to the geometry and the innovative nylon-reinforced energy rods (Adidas's clever answer to a traditional midsole plate). Heel strikers, in particular, might find the platform feels less stable initially. We strongly advise putting in a few long runs with the ASU2 before your big race day. This will not only help you get accustomed to its unique feel but also allow you to fully harness its incredible efficiency.
The Outsole: Grip That Inspires Confidence
Featuring an updated Continental outsole with longer lugs than its previous version, the ASU2 is ready to tackle whatever the trail throws at it. We tested these during winter conditions, dealing with snow and slippery surfaces, and the shoe delivered remarkably reliable grip. The varied lug pattern is a masterclass in design, providing unwavering confidence on both ascents and descents. It offers superb traction exactly where you need it, without feeling overly aggressive or clunky on smoother sections of the trail.
The Verdict: Ready to Conquer?
The Adidas Agravic Speed Ultra 2 is unequivocally built for conquering long distances and achieving high speeds on the trails. It truly shines in extended runs and ultra-distance races where energy return, sustained comfort, and pure efficiency are paramount. Invest a little time to truly understand its geometry, fine-tune the fit, and we guarantee the ASU2 will reward you handsomely out on the trail.
