Steering wandering slightly driving straight

[KinLoud]

Last couple of days noticed my AE111 4afe corolla wagon is wandering slightly when driving.
It's not easily noticable when turning (open road speeds)
I'm a bit fussy about handling..... So this is annoying.
I've checked tyre pressures
Jacked it up checked for loose bolts/joints/bushes etc
Checked for wheel bearing play
Wheel nuts are tight
Nothing is obviously wrong
Comments, questions, suggestions please

Wheel alignment? Doesn't take much of a pothole or kerb tap to knock it out a bit.

Toe might have been knocked a bit as suggested. Also check tyres for delamination/bulges/out of round etc.
