Adidas Takumi Sen 9 vs Takumi Sen 8: What Changed and Which One to Pick

Introduction

The Adidas Takumi Sen line has earned a reputation as one of the most track-spike-like road racing shoes you can buy. The Takumi Sen 8 was one of the standout picks of its release year, a shoe that felt at home anywhere from fast tempo sessions to races up to the half marathon distance. Now the Takumi Sen 9 arrives with the same midsole recipe and a revised upper aimed directly at the line’s few weak spots.

This comparison walks through what stayed the same, what changed, and which version makes the most sense for your racing plans.

Adidas Takumi Sen 9: The Refined Update

The big story with the Takumi Sen 9 is what did not change. The midsole carries over the same proven combination of Lightstrike Pro foam and a Continental rubber outsole, delivering the snappy, responsive feel that made the previous model a favorite. Adidas describes it as a track spike for the road, and the feel backs that up: quick toe-off, sharp ground contact, and a controlled ride that digs into the pavement thanks to the Continental rubber.

Where the 9 genuinely improves is the upper. Adidas took consumer feedback and reworked the fit, adding more overlays to strap the foot down for a tighter lock-on. That addresses the extra room some runners noticed around the forefoot in the previous version. The upper stays extremely breathable, using the same material as Adidas track spikes, which should make summer racing and hot-weather tempo sessions noticeably more comfortable.

Adidas Takumi Sen 8: Still a Great Pick

The Takumi Sen 8 remains a genuinely excellent racing shoe, which is why it landed on year-end best-of lists despite arriving late in its release window. It pairs the same Lightstrike Pro midsole with Continental rubber for a ride that excels in anything under a half marathon, from parkruns to 10Ks to quick half marathon efforts.

If you can still find the 8 in your size, it delivers nearly the same on-road experience as the 9. The main differences are fit related: a bit of extra forefoot volume and a slightly less structured upper. For runners who liked a touch more wiggle room up front, that could even be a point in its favor.

Which One Should You Buy?

For most buyers, the Takumi Sen 9 is the safer pick. The upper improvements are targeted at the exact complaints people had with the 8, and the midsole formula that made the 8 special carries over untouched. If you race in warm conditions, the more breathable spike-inspired upper is a meaningful upgrade.

The Takumi Sen 8 still makes sense if you find it discounted or out of stock everywhere else. Its ride quality is essentially identical, and the slightly roomier forefoot suits runners who found the original fit too snug. Availability will likely be the deciding factor as stock winds down.

Fit and Sizing Notes

Here is good news for anyone replacing an older pair: the Takumi Sen 9 uses the same last as the Takumi Sen 8. The two shoes run long in the same way, so if you wore a specific size in the previous version, you can order the same size in the new one with confidence.

Both versions favor a performance fit, so runners between sizes or used to roomier daily trainers should try them on first when possible.

Conclusion

The Takumi Sen 9 is a focused update rather than a reinvention: same beloved midsole, same road-gripping Continental rubber, same spike-like personality, with a tighter and more breathable upper on top. The Takumi Sen 8 remains a strong alternative if you prefer a touch more forefoot room or can find it at a lower price. Either way, you are getting one of the sharpest road racing shoes available for distances up to the half marathon.
