Our verdict
Adidas kept the second Agravic Speed Ultra fast and fussy, and fixed most of what people disliked about the first. The upper is far comfier than on the original Speed Ultra and the lugs bite harder, and the reviews we read broadly agree most runners will prefer it. It is still a trail racing shoe with a narrow heel, a pointed toe box and a rocker that wants you up on your forefoot. Women's Running UK gave it five stars as an ultra racer for runners who put speed and control ahead of plush cushioning. On our spec sheet it is effectively zero drop, and lab testing says the heel rocker makes it feel less flat than that. At a £200 RRP it sits alongside the S/Lab Genesis 2 and Tecton X 3 as a race-day trail shoe. If you land midfoot and race on fast, runnable trails, we'd pick it over both. Heel strikers and wide feet should look elsewhere.
Key features
- Zero-drop platformKeeps your heel and forefoot at virtually the same height, so you run over the midfoot rather than rocking back onto your heel.
- Aggressive heel rockerRolls you forward at pace and makes the flat platform feel less extreme than the numbers suggest.
- Lightstrike Pro midsoleGives you a springy, responsive ride that reviewers compared to a road racer, tuned slightly softer for ultra distances.
- Deeper, sharper lugsBite harder on rock, gravel and wet singletrack than the first version, with grip that tested among the best in the lab.
- Highly breathable upperSheds heat and drains quickly, useful on hot race days and wet courses.
Who it suits
Who should buy it
- Midfoot and forefoot strikers who race ultras and want road-racer energy on trail
- Fast runners on runnable or moderately technical courses where grip matters
- Runners with narrow to average feet who like a locked-in race fit
- Owners of the first Speed Ultra who found its upper uncomfortable
Who should not buy it
- You heel strike, because the narrow, bevelled heel gives you little support
- You have wide feet or feet that swell a lot, since the toe box tapers
- Your ultras involve lots of hiking, where the firm, forward ride offers little
- You run deep mud, as the lugs are not long enough for it
- You want one trail shoe for easy miles, which is where it feels least forgiving

Extra information
Fit & sizing
Start with your usual size. The reviews had it true to size, and one tester who went half a size down in the first version was back to their normal size in this one. Lab measurements put the internal length a touch on the long side, so there is a little room in front of the toes but not much. Width is where opinions split. One review found it slightly roomier than before, while lab testing measured a toe box well below average width and tapered at the front. Women's Running UK called the fit snug and race-ready, with excellent heel and midfoot hold but a toe box that could feel tight late in a long race. One US tester also had rubbing over the big toe joint. If your feet are wide or swell a lot over ultra distances, this is a shoe to try on before race day. For narrow to average feet it locks down well.
Performance breakdown
Ride & feel
This is a shoe that rewards pace. Reviewers describe a snappy, propulsive ride with the kind of rebound you normally get from a road racer, and the rocker rolls you forward once you are moving quickly. Drop to an easy jog, though, and it changes character: one UK reviewer found it firm and a bit unforgiving at relaxed paces. It also expects a midfoot or forefoot landing. Two of the reviews said so directly, and lab testing backs them up with a narrow heel and a steep heel bevel.
Cushioning
The midsole is Lightstrike Pro, retuned to be a little softer than in the first version. It still reads as protective and efficient rather than plush. Lab testing measured it on the soft side, yet the UK review called it firm, and that gap mostly comes down to pace: at speed the foam feels lively, while at a walk-jog on a long climb you notice there isn't much give. It suits runners who want to cover ultra distances quickly more than those planning to hike half the course.
Stability
Stability depends on where you land. The forefoot is broad and planted, and the UK reviewer found it steady over uneven ground. The heel is narrow with very little counter support, which lab testing flagged as unstable for heel strikers. One US review added that the bouncy ride can be hard to control on technical descents, with less margin for error than calmer shoes. It is a neutral shoe with no stability features, so overpronators and tired heel strikers late in an ultra are the runners it suits least.
Upper & comfort
Comfort is the biggest change from the first version. The tongue now has much more padding, and reviewers reported better heel comfort thanks to a redesigned collar. Breathability tested exceptionally high in the lab, which helps on hot days and when it dries out after a river crossing. The trade-off is durability: lab testing rated the upper and heel lining weak, and one tester noticed the tongue bunching. Expect the outsole to outlast the mesh.
