Topo-isomorphisms of irregular Toeplitz subshifts for residually finite groups

For every countable residually finite group G and every totally disconnected metric compactification \overleftarrow{G} of G , we construct an irregular Toeplitz subshift X\subseteq \{0,1\}^{G} whose maximal equicontinuous factor is \overleftarrow{G} and such that X is a topo-isomorphic extension of \overleftarrow{G} . When the acting group G is amenable, our construction yields new examples of mean-equicontinuous dynamical systems.
