The shoe is always too small. Anyone who runs Asics knows that. Normal size 44 has always been 46 here. Regarding the shoe itself, the last thing I had was the Kayano 24, which somehow never really wanted to become my friend. 4 generations later everything is right again and I am super satisfied. Comfortable to wear on the foot, good support and pleasant cushioning on decelerated runs. Definitely recommended for heavy runners.
