The interaction properties of cold dark matter particles candidates are known to lead to the structuring of dark matter on scales much smaller than typical galaxies. This translates into a large population of dark matter subhalos inside our Galaxy, which impacts the predictions for direct and indirect searches. We present a model for this subhalo population that accounts for the gravitational effects experienced by those structures (tidal stripping and disk shocking) while remaining consistent with dynamical constraints. The subhalos mass density and annihilation profiles are derived. The impact of subhalos on indirect searches with cosmic rays antiprotons is evaluated using the latest data from the AMS-02 experiment.
