My comments were not aimed at specific individuals, only at the tendency to sometimes see complexity where none is involved. Or a desire to see a quick resolution when such is not possible.
Most "tripping" will be solved by the simple stuff like correct trimming, shoeing, riding, tack usage, conditioning, etc. This does not rule-out more complex causes but means you do the simple stuff first and see if it works. If it doesn't then determine why.
Some of these simple things take some time to work. It takes time, for example, to grow out a foot. If the issue is a "long, low trim" then a correct trim requires some Tincture of Time to be effective. It might take two to four six to eight week cycles before the problem is resolved (particularly now when hoof growth slows). Usually you'll see some improvment (even though it might be minor) within a reasonable time (not more than a couple of weeks). But the human must be patient; that can be hard to do.
