crouching with dead silence really is the only counter. that's why people hate it so much. however, if you are an experienced player, you are probably able to judge where you can run and where you should better slow down to a crouch, depending on map, situation and game mode. remember that sitrep pro doesn't just give you directional audio clues of footsteps, it also let's you identify the nature of the ground it is stepped upon (wood, concrete, grass etc.). so sometimes, even if i can't figure out the direction (e.g. too many explosions going on), i know where the enemy must be because i can hear footsteps on wooden planks or similar and know there are in this or in that building.

everything has its downsides though, even sitrep pro. it is pretty much useless in e.g. drop zone as there are explosions every other second. makes soundwhoring difficult.
