Adidas Adizero Takumi Sen 10 vs Adidas Adizero Takumi Sen 11:
Which to Choose

The honest headline here is that these are extremely close relatives, not two different shoes. Both ride on full-length Lightstrike Pro, a TPEE-based superfoam, stiffened by full-length glass-fiber EnergyRods 2.0 — so neither shoe has a carbon plate; they share the same composite-rod propulsion system, which is why both feel firm, snappy, and forefoot-driven rather than plush, and why both come alive at speed but feel stiff and unforgiving at an easy jog. The low-stack geometry carries over almost unchanged: heel stack sits at essentially the same ~30.6 mm on both, so the sharp ground feel and planted, close-to-the-road transition are shared traits. The concrete differences are modest. Weight is the clearest one: the Sen 11 comes in around 184 g in a men's US 9 versus roughly 200 g for the Sen 10, so the successor is noticeably lighter — the payoff of a new, thin Lightlock woven upper and a trimmed build. The forefoot stack rises slightly, from about 22.8 mm to 23.7 mm, nudging the drop from 6 mm up to 7 mm and giving the 11 a fractionally more pronounced forefoot ramp. The 11's Lightstrike Pro is also tuned to feel a touch livelier and bouncier, though it reads as firm and narrow with little margin for an off-center landing — as does the 10. Both peak in the same 3:00–3:30 min/km zone, both name the 5K as their sweet spot, and both trade long-term durability for low weight through minimal outsole rubber and a bare-bones racing upper.
