  The suppression of the mean field temperature of the superconducting
transition, $T_c$, in homogeneous amorphous wires is studied. We develop a
theory that gives $T_c$ in situations when the dynamically enhanced Coulomb
repulsion competes with the contact attraction. The theory accurately describes
recent experiments on $T_c$--suppression in superconducting wires, after a
procedure that minimizes the role of nonuniversal mechanisms influencing $T_c$
is applied.
