Adidas Takumi Sen 8 vs the Competition: Four Racing Shoes Worth Comparing First

Introduction

The Adidas Takumi Sen 8 sits in an awkward spot. It is genuinely light, grippy and quick, but after more miles in it, it reads less like a super shoe and more like a specialist racing flat with a premium price. Before committing to it, it is worth weighing it against four shoes that overlap in features and price: the Adios 6, the Endorphin Speed 2, the Adios Pro 2 and the Hoka Rocket X.

Adidas Adios 6: The Better Everyday Package

At £110 in the UK, the Adios 6 undercuts the Sen 8 by around £60, a gap that matters for most buyers. To the untrained eye the two look similar, but the ride is very different. The Adios 6 has a slightly higher stack height, a light and flexible upper, and Lightstrike foam in the heel that gives it a more solid and responsive feel than the compressive heel stack of the Sen 8.

That firmer heel section seems to accentuate the Lightstrike Pro in the mid and forefoot, creating a slingshot-style transition from midfoot landing through to toe-off that the Sen 8 lacks. The Sen 8 is the lighter shoe by roughly 60 grams in a typical size, but the Adios 6 balances weight and construction better. On price, fit and versatility alone, it is the stronger pick for daily runs and faster sessions alike.

Saucony Endorphin Speed 2: The Versatile Trainer-Racer

The Endorphin Speed 2 brings a slightly more aggressive drop and a nylon plate into a racer-trainer format. It is only five or six grams heavier than the Adios 6 in comparable sizing, and the nylon plate does a better job of adding propulsion at toe-off than the feel of the Sen 8’s rods, which can seem a little absent in the midsole.

Where the Sen 8 fights back is the outsole: its rubber is more reliable and its grip keeps improving with use. But versatility tips the balance the other way. The Speed 2 handles slower miles, longer runs and quick sessions, and plenty of runners have even taken it to marathon distance. At £10 less than the Sen 8, it is the easier shoe to live with.

Adidas Adios Pro 2: The Full-Fat Super Shoe

For only £10 more than the Sen 8, the Adios Pro 2 delivers far more shoe. It is about 30 grams heavier in a UK size 11, which is barely noticeable, and in return you get more cushioning, an enhanced upper feel and a 10mm drop that feels more aggressive than the Sen 8’s 6mm.

The energy rods tell the story. The Sen 8’s rods are noticeably thinner and flex far too much, while the Pro 2’s rods feel rock-solid and add real rigidity and propulsion around the arch. Put more energy in and you get more out. This is Adidas’s marathon shoe, and as a complete package it simply offers more per pound than the Sen 8.

Hoka Rocket X: The Most Direct Rival

The Rocket X is the closest matchup here. Its heel-to-toe drop and stack heights are almost identical to the Sen 8’s, and it is only marginally heavier, around an ounce, partly because the test pair is a half size larger. If you found the Sen 8 too narrow, the Rocket X’s more generous upper could be the answer.

The full-length carbon plate set into the cushioned midsole gives a more propulsive, engaging and consistently smooth ride than the Sen 8, whose rods provide little propulsion or rigidity around the arch and let the shoe flex too much. It is £40 cheaper at retail, with pairs seen under £100 in the UK, making it as much as £70 less than the Sen 8. Runners have raced everything up to the full marathon in it successfully, which makes it the more usable shoe overall.

Overall Buying Advice

If you race short 5K and 10K events frequently and value minimal weight above all, the Sen 8 can still make sense. For nearly everyone else, the alternatives are stronger: the Adios 6 for everyday versatility at a lower price, the Endorphin Speed 2 for one shoe that does everything, the Adios Pro 2 for a proper super shoe at just £10 more, and the Rocket X for a carbon-plated racer that costs far less and feels better balanced.

Conclusion

The Takumi Sen 8 is a capable, very light racer with excellent grip, but its modest drop, flexible energy rods and high price leave it outgunned by its own stablemates and its rivals. The Adios Pro 2 and Rocket X in particular offer more propulsive, engaging rides for similar or considerably less money, and the Adios 6 and Endorphin Speed 2 cover everyday training more convincingly.
