Depending on how marked it is, you might be able to deal with it with an interior heel wedge.
I actually had a supination issue in my younger days, and it's swung over to pronation. But whatever footbed you try, the base needs to be solid, not a cushion. That slight buildup under the heel is often just what's needed to align the ankle bones and eliminate slight pronation. I've been using the Superfeet Black for some years to take care of my pronation. I've found that up to a 2 degree cant can be effected on a good footbed.
You wouldn;t think that heel canting would make a difference in cycling, where the contact is at the BallOfoot - but it does.
Otherwise, if the pronation is more than mild, a podiatrist may be able to make a footbed which can fit into your cycling shoes.
Canting/wedging the cleats can be a process...
