These highly aromatic shoe trees fill the width of the shoe satisfactorily. However, because the forepart is low, it doesn't exert sufficient pressure against the vamp (upper part of shoe). Barely contoured, it looks virtually flat. In a size large, it measures 1.75" from top to bottom at the highest point. My other shoe trees, on the other hand, are 2" high at the same spot.

The objective is to smooth out the wrinkles in the leather, but when the vamp is not completely filled, this won't happen. My shoes developed deep creases despite the use of these shoe trees. It's not advisable to go up one size, as the shoes will likely overstretch at the width.

Since they inadequately fulfill one of their most important functions, these shoe trees are not recommended.
