adidas Adizero Adios 9 vs Adizero Takumi Sen 11

The adidas Adizero Adios 9 and the adidas Adizero Takumi Sen 11 are both lightweight speed options, but they serve slightly different purposes. The Adios 9 is the lighter of the two, with a very low stack that emphasizes ground feel and quick turnover. It uses a partial plastic shank to add a touch of stiffness, while keeping the ride stripped-down and minimal. The Takumi Sen 11, on the other hand, has a bit more stack and cushioning underfoot, making it more protective for slightly longer efforts. It replaces the shank with carbon fiber rods, which provide a stiffer feel but also make the shoe a bit less connected to the ground.
