Adidas Adizero Takumi Sen 8 Review: A Lightweight Racer for Short, Fast Racing

Introduction

The Adidas Adizero Takumi Sen 8 sits below the Adios Pro 2 in the brand’s racing lineup as the lower-stack, lightweight option for shorter events. Where the Adios Pro 2 targets longer races, the Takumi Sen 8 is built as a 5K and 10K racer, and it comes in cheaper: £170 in the UK or $180 in the US.

It is also a genuinely light shoe. A UK size 9 weighs 194 grams, and the stack is 33 millimeters at the heel with a six millimeter heel-to-toe drop. On paper, that is a modern take on the classic racing flat, and after extensive testing in hard sessions and races, it largely delivers on that promise.

Who This Shoe Is For

This is a shoe for runners who race short and train fast. It thrives on interval sessions, track work, parkruns, 5K and 10K races, and anything up to around half marathon distance. Testers found it punchy and lively from the first run, the kind of shoe that makes you want to run fast the moment you lace it up.

If you are shopping purely for a marathon super shoe, this is not the obvious pick. It is more minimal on the foot than many alternatives, and while it is versatile enough to cover longer efforts, its clear strength is short, aggressive racing.

Fit and Sizing

Fit is the most divisive aspect of this shoe. The Celar mesh upper is thin and stripped back, with minimal padding around the heel and essentially nothing on the tongue. For runners with narrow feet, the fit is close to perfect: snug, hugging, and locked-in in a way that feels like a proper racing shoe.

Runners with high-volume or wider feet report a different experience. The shoe comes up narrow across the midfoot, and getting into it can require loosening and readjusting the laces every time. Once on, it settles down and feels comfortable, but that entry ritual is a real annoyance for some.

Length-wise, there is enough room in the toe box that going up half a size is not necessary, and doing so would only add unwanted width. If you have narrow feet, buy your normal size with confidence. If your feet are wide, try before you buy or consider alternatives with more accommodating uppers.

Ride and Performance

The midsole is full-length Lightstrike Pro, Adidas’s best foam, with energy rods in the forefoot. These rods are thinner and more flexible than those in the Adios Pro 2, and possibly glass fiber rather than carbon, but they deliver a similarly snappy toe-off and transition. There is no heel plate like the Adios Pro 2, though the shallower midsole cutouts keep the shoe feeling stable even when heel striking or running tired.

On the road and track, the ride is firm but never harsh. At fast paces it is brilliant: light pickup, quick transition, and a natural midfoot-to-forefoot contact. It even surprised on a 10K at around marathon pace, where the forefoot rods still contributed a real sense of propulsion. One tester ran reps as short as 200 meters indoors alongside flats and spikes and found it just as fast, with slightly less grip than spikes on tight corners.

The outsole combines thin tacky rubber at the heel and along the side with a Continental rubber section at the toe-off, giving excellent grip for attacking corners at speed in short races. Compared with softer super shoes, the Takumi Sen 8 feels firmer and more connected, with more midsole protection than shoes that let you feel the ground rising up. It is noticeably firmer and more minimal than the Adios Pro 2, but arguably more stable despite the cutaways.

Things to Consider Before Buying

The narrow fit is the main hurdle. If the upper does not hold your foot comfortably, you will find reasons to reach for other shoes, no matter how good the ride is.

Competition is the second consideration. If you already own a Vaporfly, it will do just as good a job over short races, and the Takumi Sen 8 may not add enough to justify a second purchase. The Asics Metaspeed Sky offers more range at a higher price, with a full-length carbon plate and a 33 millimeter stack that covers everything from 5K to marathon. The Takumi Sen 8 is a strong alternative to super-high stacks, but it is not cheap enough to be an impulse add-on.

Buying Advice

Buy this shoe if you race 5K to 10K, do targeted speed sessions, and prefer a firm, locked-in, connected ride over tall, soft stacks. It is one of the more enjoyable short-distance racers available, and it does a better job as a racing-flat replacement than most. Up to half marathon distance, it holds up well, and many runners would happily race a half in it.

Skip it if you want one shoe to cover the full race calendar, if you already own a Vaporfly and are happy with it, or if your feet are wide enough that the upper will fight you every run. For the right runner, though, it is a lot of fun and delivers exactly what it promises.

Conclusion

The Adidas Adizero Takumi Sen 8 is a very highly rated, lively, punchy racer that makes hard sessions something to look forward to. It is not a necessary purchase for everyone, and the narrow fit and stiff competition make it a considered buy rather than an obvious one. But for short, fast racing, it delivers exactly what it sets out to do, and it is one of the standout racing shoes of its generation.
