Lol sorry. I should have been more specific. Well first is it possible for a shoe tree to strech out a pair of shoes by like half a size? If so, is it also possible to get them back to the way they were when I first bought them. It's because I have a pair of shoes that seem half a size bigger and I'm starting to think it's because of the shoe trees..
Sorry, I couldn't resist George Constanza.
I don't think it would be possible unless maybe during a complete resole, if they put the upper on a half smaller last???? I really have no idea how they could make it smaller. I agree, with the others, the tension put on by the trees is nothing (if I had to guesstimate less than 3%) compared to your foot, while walking and standing. That being said, do yo have to jam the tree into the shoe to the point beyond where the spring is fully compressed?
Also, I find I really don't like the Nordstrom trees as much as the Allen Edmond ones. The spring action on the Nordstrom doesn't seem as smooth, but maybe I just got a bad example, I haven't tried the J.A. Bank ones, but I have a feeling they're all made by the same company, maybe to different specs.
