The neutron skin of $^{208}$Pb has received considerable attention in recentyears. A variety of strongly-interacting probes depict a rather consistentpicture but pionic probes have not been referred to in this context. We presenthere neutron-skin values from pionic atoms and from total reaction crosssections of $\pi ^+$ between 0.7 and 2 GeV/c which fit well into the picture.In addition we show that a neutron skin for $^{48}$Ca can be obtained fromexisting data on pionic atoms and the result agrees with pion scatteringexperiments and with the scattering of $\alpha $ particles.
