A characterization of radial Herz-Schur multipliers on groups which are free products \(G=*_{i-1}^{N} G_{i}\) of subgroups of the same order (finite or infinite) is given. The multiplier norm is computed in terms of trace norms of appropriate trace operators. This applies in particular to free group
