Hmm, good question. It doesn't seem like there would be a major difference between compact and "full" sized shoe trees. As long as they fit, the shoe trees are doing the just of their job. I hope you find a solution.

I'm pretty convinced that shoe trees are intended solely to keep the form of a shoe. But, no one has brought up the aromatic design, those shoe trees with funny holes in them. Surely, they are supposed to promote better circulation? Do they enhance absorption (if wood, of course)?
