Adidas Takumi Sen 8 First Run Review: A Lightweight Racer That Rewards Hard Efforts

Introduction

Some running shoes arrive with quiet expectations. The Adidas Takumi Sen 8 arrived with loud ones. It is a shoe many runners have been waiting to see tested properly, and the honest way to find out what it offers is to push it hard over a genuinely demanding workout. That is exactly what happened in this first run: a warm-up, sixteen reps of 60 seconds on with 30 seconds off at just under 5k pace, a short break, and then a 10k block at a pace slightly slower than marathon effort.

It is a workout that covers a wide range of paces, which makes it a very good test for a shoe positioned somewhere between a racing flat and a full super shoe.

Who This Product Is For

The Takumi Sen 8 is built to be a lightweight racing shoe geared toward 5k through half marathon distances. If you want a shoe that explodes off the line on short, hard reps while still carrying some of the modern super shoe feel, this sits squarely in that territory. Runners with easy mileage in mind have other options, but if speed sessions and shorter races are where your shoes earn their keep, this is a very interesting proposition.

A Serious Test From the Start

The session started with the interval block, and the shoe delivered almost immediately. The reps came out around 3:05 to 3:10 per kilometre, and the standout quality was the light pickup. The shoe really explodes up, and even when turnover started to fade toward the end of a rep, getting it going again was easy because it is so light to pick up.

Pushing hard and getting up onto the midfoot and forefoot also put a lot of force through the midsole, and you can feel a response there from the rods. That energy return is a genuine part of the experience, not just marketing copy.

Design and Specifications

The Takumi Sen 8 has a slightly lower stack than the Adios Pro 2: 33 millimetres at the heel and 27 at the forefoot, giving it a fairly low six-millimetre drop, though on the run it did not feel especially low. In a UK size 9 it weighs 194 grams, about 6.8 ounces, which is where much of its charm lives.

The midsole uses Light Strike Pro, Adidas’s top foam, with energy rods under the forefoot that are slightly thinner and lighter than the Adios Pro 2 versions, reportedly made of glass fibre rather than carbon fibre. There is an extra cutout in the midsole beyond the chunky cutout seen on the Adios Pro 2, again saving a little weight. The upper is a very lightweight Celamx mesh with no real heel counter at all, flexible and loose, with a nice racing fit. It runs slightly smaller and tighter than the Adios Pro 2 in the same size, narrowing a little around the midfoot, but true to size still feels right.

Outsole grip comes from an extended piece of Continental rubber around toe-off and forefoot landings, with a textile rubber strip along the other side and rear of the shoe adding protection for other foot strikes. The price is 170 pounds in the UK and 180 dollars in the US, only 10 pounds cheaper than the Adios Pro 2, so it is priced as a similarly serious racing shoe.

How It Performed on the Run

The 60-second reps were where the shoe felt best. Lightweight, propulsive, and responsive, it made hard efforts feel manageable and kept the legs turning over. But the interesting part came afterward, on the 10k block at around 3:35 per kilometre.

At slower paces, where a heel strike comes into play, the shoe held up better than expected. The transition felt smooth, and there was still a noticeable tip-forward sensation from the rods despite the low drop. It almost feels like a blend of the Adios Pro 1 and Adios Pro 2: the nimbleness and lightweight pickup of the first, plus the smooth rolling control of the second at hard, sustained paces.

It is worth being honest about the trade-offs. It does not feel as cushioned and smooth at easy paces as the Adios Pro 2, and there was a slight hot spot under the forefoot late in the workout, though nothing genuinely uncomfortable. The lower stack helps around corners: it is more stable than very high-stack shoes, and you can be more aggressive into bends. Still, at 33 millimetres of heel stack, dead turns and sharp corners demand care. This is not quite a return to the old racing flat experience.

Things to Consider Before Buying

The price sits close to the Adios Pro 2, so this is a considered purchase. The fit runs a touch smaller and tighter than the Adios Pro 2, which matters if you are between sizes. And while the shoe handled a workout of roughly 20k total very well, including hot spots only late in the session, marathon distance may still favor the Adios Pro 2 with its extra cushioning and wider base at the back when form starts to fade.

Buying Advice

If your racing life centers on 5k to half marathon, and your training includes serious speed work, this shoe deserves a place on your shortlist. It rewards effort, feels wonderfully light under 200 grams, and still carries enough super shoe character to feel modern rather than retro. For longer, more cushioned race days, the Adios Pro 2 remains the safer pick.

The Verdict So Far

This is only a first run, and more testing is planned, including more miles and a race if possible. But the early impression is overwhelmingly positive. The shoe lived up to the anticipation: fantastic on the fast reps, better than expected on the 10k, and genuinely fun to run in. The idea of slightly lower stack super shoes looks like a good one, and Adidas appears to have a real winner here.

Conclusion

The Adidas Takumi Sen 8 is a lightweight, low-stack racer that shines on short, hard efforts and holds its own surprisingly well at sustained tempo paces. With 33 millimetres of heel stack, energy rods under the forefoot, and a 194-gram build, it offers a bit of everything in a lovely way. If shorter races and fast sessions define your running, it is a very easy shoe to recommend as one to watch for a full verdict after more miles.
