So far, I only have the AE full toe shoe trees and they seem to fill the toe area pretty well, either all the way in or at the most, there's no more than 1/4" from the very tip, even in my 5-last shoes/boots. It appears from the above post, that the combo-trees are somewhat slimmer and can fill narrow shoes deeper. Then again, being slimmer, wouldn't they fill the sidewalls less?
Overall, what are the main advantages/disadvantages to full vs combo? I could still use at least half dozen sets and while I like the full AE trees, the NR Woodlore Combos for half the price is somewhat appealing. Is it worth twice as much for the AE's?
Most of my shoe trees are Woodlore from the Rack.
