| Abstract: | We present the first results of our ISO program on High-Mass X-ray Binaries (HMXBs). Infrared photometry, obtained at different
aspect angles of the systems, is used to investigate the massive star's disrupted stellar wind and the accretion flow towards
the compact X-ray source.
Scenarios for massive binary evolution predict that HMXBs receive a large kick velocity during the supernova explosion of
the compact star's progenitor. One might, therefore, expect to observe wind bow shocks around these systems such as observed
around many OB-runaway stars. Such a wind bow shock has recently been discovered around the system Vela X-1.
