Woodlore must use Johnston and Murphy shoes as their  model for manufacturing these shoe trees -- they are a perfect fit.  They hold my dress shoes in a perfect shape and leave them smelling faintly of cedar.  They also look very nice -- the brass knob in the back is useful and classy looking.  Outstanding quality and design.  I bought the XL model for my size 13 shoes using the guide from woodlore.  Amazon delivered them in two days at a very competitive price.
