When it comes to adidas racing shoes, do you picture ADIZERO and that aggressively rocked forefoot? That characteristic also shows up in adidas' trail running shoes. The pronounced roll delivers a downhill "speed-descent weightlessness" sensation, echoing the series name AGRAVIC (literally "weightlessness"). The top long-distance racing shoe AGRAVIC SPEED ULTRA (Big Speed Meteor 2) features an unusually pronounced forefoot rocker for a trail shoe, and an equally exaggerated rear heel. It also uses upgraded LIGHTSTRIKE PRO foam + TPE claw-shaped energy columns, giving the midsole top-tier, matrix-style feedback. Seen from the side it looks like a roly-poly toy, with strong fore-and-aft rocking. In practice that geometry raises the handling threshold. One curiosity: will the next-gen Big Speed Meteor borrow EVO 3's design? If so, would that mean an even more aggressive style? Because the former's threshold is so high, the AGRAVIC SPEED 2 nicely serves as a lower-tier alternative to the Big Speed Meteor 2. A milder rocker significantly lowers the handling barrier; the thin sole and dual-density foam design without plates provide more stable control and feedback, and are also well-suited to technical terrain. Being lighter, it can also be an effective short-distance racing weapon for elite athletes. Also, the uppers of these two models—heavily criticized last generation—have been replaced this time with more comfortable, lightweight mesh uppers. So for recreational runners, does adidas offer a slightly "thicker" trail running shoe? The AGRAVIC SL borrows from the road training ADIZERO EVO SL design, and is more like a "thicker" version of the AGRAVIC SPEED 2. Using a single piece of LIGHTSTRIKE PRO foam with no plates, the cushioning feels more natural and comfortable; combined with a milder rocker... this shoe is easier for recreational runners to handle across mixed mid- to long-distance terrain. If you want a touch of racing DNA, consider the AGRAVIC TT. It's a performance-oriented shoe targeted at technical terrain. Its dual-density midsole uses resilient-yet-supple LIGHTSTRIKE 3.0 as the main framework and base, while LIGHTSTRIKE PRO on the upper layer runs 3/4 length to provide a lively underfoot feel. A protective plate is inserted between the two midsole layers, which also contributes some propulsion. If your ability isn't that high, try this softer shoe that still offers propulsion and feedback. The AGRAVIC LITE is more "beginner-friendly" and a good tool for developing trail running skills. A thinner sole increases ground feel, a reinforced heel wrap improves lockdown, and the Continental lugged outsole ensures grip. The resilient LIGHTSTRIKE 3.0 won't feel overly soft under fatigue and overtax your arch.
