  Runaway, massive stars are not among the most numerous. However, the bow
shocks built by their supersonic movement in the interstellar medium have been
detected in the infrared range in many cases. Most recently, the stellar bow
shocks have been proposed as particle acceleration sites, as radio data
analysis at high angular resolution have shown. We present results of different
manifestations of the stellar bowshock phenomenon, revealed from modern IR
databases.
