LOL to the guy who said surefoot make good footbeds, they are actually one of the worst footbeds you can get, there not even really custom.
Superfeet are slightly better but the best you can get is a well made Sidas conformable.
The issue is you need a very good boot fitter to make one. A Sidas footbed made by a bad bootfitter will be as bad as a surefoot or superfeet kork.
Do your research and find the best bootfitter you can. This may well mean a road trip but it will be worth it.
