Vintage Riedell Roller Skate Boot Men's size 9

My family were artistic roller-skating club skaters in the late 80's and early 90's when these boots were last used, they've been sitting in a closet since. They are in excellent condition for their age, the leather is still in great condition and the foam on the tongue is still soft and pliable but is showing a bit of wear on the top two to three inches. They have been drilled for roller skate plates at some point but I don't know the plate size. The boots are stamped "M9 PR" on the bottom.

This item is one pair of boots and a Reidell box. Not a complete pair of skates.
