  In theories with conserved dipole moment, isolated charged particles
(fractons) are immobile, but dipoles can move. We couple these dipoles to the
fracton gauge theory and analyze the universal infrared structure. This
uncovers an observable double kick memory effect which we relate to a novel
dipole soft theorem. Together with their asymptotic symmetries this constitutes
the first realization of an infrared triangle beyond Lorentz symmetry. This
demonstrates the robustness of these IR structures and paves the way for their
investigation in condensed matter systems and beyond.
