Adidas Adizero Takumi Sen 10: A Familiar Speed Shoe With Small But Meaningful Updates

Introduction

The Adidas Adizero Takumi Sen has been one of the most beloved short-distance speed shoes of the past two years. Versions 8 and 9 shared the same midsole with only a slight upper revision, and that consistency is part of why the shoe earned its following. The Light Strike Pro foam paired with glass fiber energy rods delivers a firm, snappy, fast ride that hearkens back to the days of pure, simple running flats.

Adidas essentially pioneered the 5K racing shoe category, and a whole new batch of competitors has followed, including the Nike Streakfly, Saucony Sinister, and Hoka Cielo Road. Even so, many runners still place the Takumi Sen at the top of the short-distance racing and speed category, which means version 10 has a lot to live up to.

This update takes an evolutionary approach rather than a revolutionary one. The stack, the overall ethos, and the core ride character carry over, while the midsole formulation, forefoot geometry, and outsole layout receive modest modernizations.

Midsole: Same Foam, Softer Feel

The Takumi Sen is designed as a 5K and 10K racing shoe with a lower stack height than a traditional super shoe. Versions 8 and 9 used a 33mm heel stack, a 27mm forefoot stack, and a 6mm drop, and version 10 keeps a very similar setup. Adidas is not messing with the formula that set the standard for what a good short-distance racing shoe can be.

The Takumi Sen has long used Light Strike Pro, a firmer supercritical TPE foam. It is not as soft as the PEBA foams in some rivals, but it provides strong energy return, particularly when paired with the glass fiber energy rods in the midsole. For version 10, Adidas appears to be using the modernized Light Strike Pro formulation seen in the Boston 12. A durometer comparison between the Boston 12 foam and the Takumi Sen 8 showed the newer formulation is moderately softened, and the expectation is a ride that sits a little softer underfoot with a more impact-absorbing feel rather than the firm bounce of the Sen 8. It is not a dramatic change, but it is noticeable.

The bigger geometric change is at the forefoot: version 10 adds more of a rocker up front. Rockers help with turnover, get you up on your toes quicker, and can lift your cadence at 5K pace or faster, especially for heel and midfoot strikers. That said, this was one of the only fast workout shoes that was not heavily rockered, and that flat character was part of its charm. It ran like a no-frills shoe: a pure, simple, fun experience that felt like a traditional racing flat from decades past. Version 10 trades a bit of that character for a modest forefoot curl, in line with the Boston 12. The contouring of the foam has also been revised slightly, with repositioned cutouts and a modernized design language, roughly 10 to 15 percent different, to align with the rest of the Adizero lineup.

Upper: Breathable But Scratchy

The upper is the disappointing part of this update. Adidas is sticking with the same setup used on the Takumi Sen 8 and the Boston 12: a lightweight, very breathable material that is scratchy and uncomfortable, almost like hardened cheesecloth. It is not pleasant when you crank down the laces, and the fit remains snug and race-like, as expected from one of Adidas’s fastest shoes. The forefoot volume may be slightly expanded at the front of the platform, but no major fit changes should be expected.

The skinny laces and super-thin tongue also carry over, and there is a fair bit of lace bite when you pull them tight to get a proper lockdown. This is the recurring flaw across the Adizero range from the Boston to the Takumi Sen: the uppers are not comfortable, and lockdowns can be sloppy depending on your foot shape. That issue does not appear to have been addressed here. One small nicety is the pop collar heel tab at the back, which gives you something to grip when slipping the shoe on.

Outsole and Durability

The outsole layout has been revised slightly, though not enough to change the wear pattern significantly. Continental rubber remains on the forefoot, where it delivers excellent grip and solid durability. The concern is at the heel: in testing of the Sen 8, the rear rubber wore through at around 100 miles, and version 10 goes with an exposed foam situation at the back, similar to the Boston 12, where the rubber is sectioned and the middle is left open.

In general, durability will not be great, but this shoe is not meant to be a high-mileage trainer. It earns its place as a shoe you reach for on your fastest workouts and the occasional 5K or 10K race. If you baby it, pulling it out a few times a week for interval sessions, you should get a year or more of use out of it. Do not expect 400 to 500 miles.

Who This Product Is For

The Takumi Sen series is a fast, short-distance speed and racing shoe, not a daily trainer. Some runners love it enough to wear it every day, but the geometry of the plate and low stack will not support muscle development the way a traditional daily trainer does, and it offers less cushioning and protection for high mileage than a max-cushion shoe would. For everyday miles, a softer, more protective trainer is the better choice.

Buying Advice

If you liked the Takumi Sen 8 or 9, you will love the 10. This shoe keeps roughly 90 percent of what worked in the last generation and makes minor updates to the upper, midsole, and outsole to bring it into the current Adizero lineup. It works for a lot of people, with one clear exception: the platform is very narrow through the heel and midfoot, so runners who need stability or have wider feet should look elsewhere.

For narrow-to-standard feet and runners who want something fast for interval training days or short races, it remains one of the best choices in the category.

Conclusion

The Takumi Sen 10 is a confident evolution rather than a rethink. The softened Light Strike Pro midsole and added forefoot rocker modernize the ride without losing the firm, snappy character that made this shoe a favorite, while the upper remains the shoe’s weakest link. If short-distance speed is your goal and your foot suits the narrow platform, this update should be easy to recommend.
