Takumi Sen 8 vs Streakfly: not comparing apples to apples
When the Adidas Takumi Sen 8 and the Nike Streakfly were announced, most people – including myself – were convinced that we would have an epic 5/10k racing shoe battle. The reality is a little bit different.
Both shoes are really lightweight (181g for the Streakfly, 207g for the Takumi Sen 8 – that is in my size US11). And both share similar stack heights and drop (32/26 for the Streakfly, 33/27 for the Takumi). But their foams and rides are very different. And it’s hard to argue that they’re both 5/10k racing shoes.
The Adidas Adizero Takumi Sen 8 has a TPE-E Lightstrike Pro foam with a durometer score of 33.6/100. Most importantly it comes with Adidas signature energy rods (a plastic version of them), which help rigidifying the forefoot.
The Nike Streakfly gets a full lenght ZoomX midsole with a durometer score of 27.3/100 (durometer scores go for 0 to 100, and the lower the softer). It has a Pebax midfoot shank (a little plate that also brings structure to the shoe, but does not run all the way to the forefoot).
For a midfoot/forefoot striker like myself, the stiffness of a shoe in the forefoot can make a lot of difference. I feel like the Takumi Sen 8 offers me what I need to push on whereas the Streakfly bends to much and has that inefficient feeling.
How they ride
The Takumi Sen 8 feels more snappy and responsive. While I probably would not race in it (no matter the distance I think there are better shoes for that), I enjoy training in it.
I can nonetheless totally understand why people will love running in the Streakfly. It’s a light and very comfortable shoe, with a soft and bouncy midsole. Ground contact combined with some decent leg protection is a rather rare thing and the Streakfly has them. I compare it a lot with the Rebel v2 and if you loved that shoe (and many people did), go ahead because it’s a more durable, more comfortable and lighter version of the Rebel.
Who they will work best for
I can see the Streakfly working better for heel strikers and cadence runners (runners that increase their cadence more than their stride length at higher paces). The Takumi will probably be a better choice for midfoot/forefoot strikers (it works fine for heelstrikers but it does not transition very quickly to the forefoot because of that “flat” geometry.
One very important thing to flag: both shoes run long and I opted for 1/2 size down on both. I would recommend you to do the same.
