In this work, we show how π+ KS femtoscopic correlations, recently reported by ALICE collaboration in pp collisions, can be well described taking into account relativistic corrections and using realistic πK interactions. These are obtained from a dispersive analysis of scattering data, which provides an accurate and model-independent description of the κ/K^*0(700) resonance pole. The chiral symmetry suppression of the πK interactions at low energies and the non-ordinary features of the κ/K^*0(700) seem to suggest that the π+ KS source radius might be surprisingly smaller than for other hadronic processes when using the standard and simple Lednicky-Lyuboshits factorization approximation.
