adidas Adizero Takumi Sen 11 vs Nike Streakfly 2

The adidas Adizero Takumi Sen 11 and 

the Nike Streakfly 2 are both built for shorter races and fast sessions, but they take different paths. The Takumi Sen 11 carries a bit more weight and sits on a higher stack, offering a touch more cushioning. Its EnergyRods add some stiffness, and in terms of raw midsole energy return, it actually has an edge. The Streakfly 2, however, is in a class of its own when it comes to efficiency at short distances. Its ultra-light build, firm forefoot, and full-length carbon plate make it incredibly snappy and efficient at higher paces, feeling closer to a track spike for the road. If you want a little more substance and protection, the adidas may suit you better, but for pure speed and efficiency over 5K to 10K, the Nike is unmatched.
