I made a similar underhanded remark in the past in this thread that echos your sentiments; looking at pictures of shoes that resemble a stock photo gets stale. Who doesn't enjoy the visual interest and unique story behind a developed patina? Often, I get little of that from meticulously maintained shoes, particularly shell.
That said, I think it depends on the intents and purpose of given footwear. If a shoe is intended for formal or business purposes, it should unquestionably be well maintained and preserved in a presentable, near-new-appearing condition. For more casual purposes, I want to see an aged patina. The notable caveat here is the sliding scale between what's "formal" and what's "casual" varies greatly depending on the individual.
Agreed. For truely formal events where shoes likely recieve very little wear and tear, it shouldn't be very hard to keep them looking pristine (especially if they are shell). However, for business purposes (I assume you mean daily office/commute, etc.) the aging progression discussed in previous posts will inevitably set in with any shoe being worn regularly. For these, the "distinguished" look should gradually set in for any high quality well cared for shoe.
