On the topic of shoe trees, my size is generally a 10 D - the last size it's recommended to get the Medium woodlore. A 10.5 D is supposed to get the large woodlore. Would it make much difference if i used a large woodlore (happen to have one, although i have some mediums as well) in the 10D? the fit is tight, but doesnt appear to be stretching out, and it doesnt take all that much effort to extract the tree. Of course, i dont want to destroy my park aves.
