We numerically investigate the impact of heat conduction by thermal electrons on the physics of colliding winds by means of a 1D model problem. Compared to ideal flows, the hot plasma has significantly lower temperatures and has both a high- and low-density component. Consequently, the shocks in WR binaries become generally more radiative and the emitted X-ray spectrum is softer, shows more emission lines, and is a composite of the emission from high- and low density regions.
