In reply to metrorat:
> I’ve had some experiences with super feet custom insoles and didn’t find them to be very good. The problem seems to me that they mould to your foot when it isn’t loaded.
I wear insoles to reduce over-pronation, and have some custom Superfeet which are great. If they'd been moulded to my loaded foot they'd have been no good because it would have built in the over-pronation.
However they aren't very cushioned, which is what the OP is looking for. Superfeet have a variety of insoles available with different amounts of cushioning. Sole are also quite cushioned.
I'd suggest taking the boots to a decent shop that has a selection that you can try.
