Adidas Racing Flats Compared: Adizero Adios 8 vs Takumi Sen

Introduction

Adidas took a deliberately different path with its 2023 racing lineup: while the brand’s super shoes get most of the attention, two lower-profile racing options show that not every fast day demands a towering carbon plate. The Adizero Adios 8 and the Takumi Sen both sit on the lighter, more traditional end of the racing class, but they take noticeably different approaches to fit, feel, and price.

Adizero Adios 8: The Featherweight Racing Flat

The Adizero Adios 8 is the eighth generation of a shoe with serious history: the original Adios held the world record over more than a decade, with the record broken three times in its first version. Despite sitting at the lower end of Adidas’ racing class at $130, it is packed with the brand’s top-tier technology.

The most striking feature is the upper. The see-through open mesh is so airy that it resembles a screen door, replicating the fit feel of a track spike. When you strap it on and take off, the shoe responds immediately. Weight figures back that up: 7.2 ounces in the men’s version and 6.1 ounces in the women’s, with construction shaved down as much as possible so that the outsole rubber is arguably the heaviest part of the shoe.

Underfoot, the Adios 8 uses a dual-density Lightstrike Pro setup: a large wedge of Lightstrike Pro in the forefoot paired with Lightstrike 2 elsewhere, plus a torsion rod system for a traditional racing flat feel. The stack is 28 millimeters in the heel and 23 millimeters in the forefoot, an 8-millimeter drop that Adidas stamps clearly on the shoe. The forefoot foam is meant to deliver the bounce and acceleration off the ground you would expect from a super shoe, without forcing that feel on every workout.

The thin build is so aggressive that Adidas suggests it could even stand in for a track spike on the track or in track workouts. If you want something fast that does not feel like a daily super shoe, this is the more traditional pick.

Takumi Sen: The Sharper Racing Tool

The Takumi Sen occupies a slightly different role. It is a thinner shoe with less stack than a marathon-day super shoe, built around a full midsole of Lightstrike Pro plus rods. That is the key mechanical difference from the Adios 8: where the Adios uses dual-density midsoles and a torsion rod, the Takumi Sen goes all-in on Lightstrike Pro throughout, reinforced with rods for a snappier, more connected ride.

In practice, the two shoes line up as similar in concept but different in feel. The Takumi Sen is positioned as a 5K and 10K racing flat, a sharper tool for race day, while the Adios 8 can stretch across 5K, 10K, and even half marathon distances and doubles as more of a training shoe for faster sessions. They also sit at different price points, with the Takumi Sen positioned above the $130 Adios 8.

Which One Should You Choose?

If you want a genuine racing flat that can handle everything from 5Ks to half marathons and double as a workout shoe, the Adizero Adios 8 is the more versatile and affordable option. Its massive forefoot Lightstrike Pro wedge gives it a bounce that its heritage suggests previous versions never had.

If you race shorter and want the most responsive, rod-stiffened Lightstrike Pro midsole for 5K and 10K efforts, the Takumi Sen is the sharper, more race-specific choice. Its full Lightstrike Pro build is tuned for fast turnover rather than everyday mileage.

Both shoes prove that Adidas still invests real technology below its flagship super shoe tier, and each rewards a specific kind of runner.

Conclusion

The Adizero Adios 8 delivers world-record pedigree, a spike-like see-through upper, dual-density Lightstrike Pro, and a $130 price tag, making it the flexible pick for training and racing alike. The Takumi Sen goes further down the racing-flat path with a full Lightstrike Pro midsole and rods for dedicated short-distance speed. Choose the Adios 8 for versatility and value, and the Takumi Sen for pure 5K and 10K race-day sharpness.
