Adidas Takumi Sen 8 Long Run Review: Can a Short-Distance Racer Go the Half Marathon Distance?

Introduction

The Adidas Takumi Sen 8 sits in an interesting spot in the brand’s racing line-up: it is the shorter-distance cousin to the Adios Pro 2, built as a stripped-back race shoe rather than a fully stacked super shoe. To see how it behaves outside its comfort zone, we took it on a long run of 13.17 miles, just over half marathon distance, on a blustery day with gusts reaching 18 mph.

That kind of wind makes everything harder, but it also makes for an honest test. If a lightweight racer can stay comfortable and composed over this distance, that says a lot about its real-world range.

Upper: Light, Breathable and Easy to Live With

The upper keeps things minimal, and that minimalism works in its favor. Paired with a good running sock, the lockdown stayed secure and comfortable across the full distance. The toebox is a little narrow, and you can feel the shoe slightly in the arch when you first slip it on, but that sensation fades quickly once you start running. This is a running shoe first and foremost, and it rewards being used that way.

One genuine strength showed up in wet conditions: after wading through puddles and standing water, the open, meshy toebox lets water in but lets it straight back out again. Nothing on the upper holds moisture, which is a real benefit for racing in unpredictable spring weather.

The laces are the weak point. They feel thin and slightly flimsy, though it is arguably the price of keeping the upper this light. At around 75 miles in, the guidance is to go true to size; there is no need to size up here, unlike some other recent Adidas models. The upper also showed no constrictive feeling in the later miles, even as feet naturally tend to swell on long efforts.

Midsole: Lightstrike Pro Keeps Getting Better

The midsole uses Lightstrike Pro, the same foam family as the Adios Pro 2, and it seems to mature with use: at around 75 miles it feels more flexible and more forgiving than it did out of the box. There is no reason this shoe cannot serve as a half marathon racer, even though it launched with shorter distances in mind.

The stand-out quality is how it behaves at pace. At easy aerobic efforts it feels fine, but turn the speed up and it comes alive. On half-mile repeats run at roughly 6:35 to 7:00 per mile pace, the shoe felt dynamite, like it genuinely wanted to move.

An unexpected bonus: the shoe felt more beneficial later in the run than at the start. When legs get heavy, the very light weight seems to give a little extra push, and there was more energy left in reserve towards the end than is typical on a long run. The drop also becomes less noticeable the more you use the shoe, and it almost encourages a slightly faster cadence than you might naturally run. For runners wanting a stripped-back half marathon option with fewer bells and whistles, this fits the brief well.

Outsole and Durability

Grip and traction on road and pavement were fantastic. The only wear visible approaching 100 miles is a small amount in the midfoot section, where the pattern on the smoother rubber has started to smooth off. Everything else looks healthy, which is promising for a shoe aimed squarely at racing rather than daily training.

One clear limitation: this is not a trail or mixed-terrain shoe. The cutaway midsole reduces contact area, and the rubber simply does not work on grassy, muddy or slippery surfaces. Road-based short and mid-distance running is the use case, and within that it performs perfectly.

Buying Advice

If you race anything from shorter road distances up to the half marathon and prefer a lighter, less aggressive shoe than the flagship super trainers, the Takumi Sen 8 deserves a serious look. It proved itself over half marathon distance without complaint, and it rewards faster pacing. Just keep it on the road, go true to size, and accept the flimsy laces as part of the lightweight package.

Conclusion

The long run did not disqualify the Takumi Sen 8 from half marathon duty; quite the opposite. It is not as propulsive or as cushioned as the Nike Vaporfly Next%, but it was never meant to be. Over the half distance it felt good, the foam is improving with mileage, and durability looks strong. For runners after a stripped-back race shoe with genuine range, this one is easy to recommend.
