The authors of the above paper call into question recent evidence on the properties of self-interstitials, I, in Ge [Phys. Rev. Lett. 110, 155501 (2013)]. We show that this judgment stems from invalid model assumptions during analysis of data on B marker-layer diffusion during proton irradiation, and that a corrected analysis fully supports the reported evidence. As previously stated, I-mediated self-diffusion in Ge exhibits two distinct regimes of temperature, T: high-T, dominated by amorphous-like mono-interstitial clusters – i-morphs – with self-diffusion entropy ≈ 30 k, and low-T, where transport is dominated by simple self-interstitials. In a transitional range centered on 475\ub0C both mechanisms contribute. The experimental I migration energy of (1.84 \ub1 0.26) eV reported by the M\ufcnster group based on measurements of self-diffusion during irradiation at 550\ub0C &lt; T &lt; 680\ub0C further establishes our proposed i-morph mechanism
