The way I setup footstep sounds is via custom anim notifies. The anim notify event fires a line trace to the ground to determine the surface type so I can play back the correct footstep sound (grass, dirt, mud, wood, concrete etc).
Take the location and pipe it to spawn sound at location. Choose your sound cue.
pretty straight forward.
