A great question
This is a short, easy-to-understand blurp written by an equine center so you know there is a difference between laminitis and founder. Laminitis is the precursor or "warning" signal the horse's hooves are headed for trouble. What Is The Difference Between Laminitis and Founder?
This link has quite a bit of detail, also written by a credible professional The Two Phases of Laminitis: News: Kentucky Equine Research
Don't depend on Wikipedia for accurate answers unless they provide links to legitimate sources
When I want serious answers, I look for .edu sites; TheHorse.com is a great place to go and membership is free; look for articles written by veterinarians (DVM's).
If an issue arises with your own horses or a friend's horse, this is a great forum to get some honest answers, for the most part.
What most of us do is give input/opinions based on our own experiences.
It's always helpful to know what other folks have done in the situation you might find yourself in --- while STILL reading the credible web sites and sometimes, after all that, you might not get the right answer because there are exceptions to every rule.
