  We study the long time behavior of solutions of periodic Fisher-KPP type
equations in $\mathbb{R}^n$ that arise from compactly supported initial data.
We prove that propagation along a fixed direction $e\in\mathbb{S}^{n-1}$ is
completely determined by an associated minimizing direction $e'$ which is
unique and in a bijective correspondence with $e$. This correspondence allows
us to determine the correct Bramson shift in higher dimensions and show that
that the propagation along each $e$ occurs asymptotically at the speed
$w_*(e)t-\frac{n/2+1}{\lambda_*(e')\,e\cdot e'}\log t+O(1)$.
