what to look for when buying secondhand leather shoes?

I’m hoping to get a pair of black loafers, and I’m looking at secondhand Aldens to stay in my budget (sub $200 since I’m not going to wear them often). I’m seeing a really wide range of prices, but all the used pairs look roughly the same to me. What should I look for when deciding if the shoes need a good polishing vs a trip to the cobbler?

Any of these listings have obvious red flags (other than the price)?
