These might be made in the USA Florsheims, given the stamp. They're definitely not Kenmoors, but they're probably comparable to a low-200 shoe NIB if made in the USA and fully leather lined. Worth asking about, and I think you maybe can negotiate the price. I think $85 is a little high, but maybe $50 to $60 if USA-made and leather-lined?
Things I would ask: Location of manufacture, whether they are fully lined or not. If negative on both, they're probably the recent $150 fairly mediocre line.
