But for their age, I have seen some in much worse condition. Leather shoe portion is very firm but still flexible. There are no cracks/tears to them, just creases, oiled very well with mink shoe and boot oil.
Shoe Laces are in good condition. Wheels all spin freely have new bearings on them. Rubber stoppers look to have a lot of life left in them.
The right one was definitely used more. 10 lace holes on each side and 5 lace hooks on each side. There is a tan thin shoe insole, which seems to be fine.
