October 21 - what to do about these?

So, yikes, I got all caught up and then bam, a few days slip by and then it's a week and I have to figure out what I wore, what I am going to discard, what needs more pics, what comes next.

Until this challenge, I never realized how many pairs of shoes I owned that were the same shoe in different colors. Black and pink. Seafoam and black (haven't worn the black in this challenge yet). Bronze, silver, and blue. Brown and black espadrilles (and I even have replacement pairs for both of those stashed away!). And I there are more I can't even remember.

So I was cleaning out my closet last week and found these (duplicates to these):
What: Size 8, square toe, 2.5 inch tan/brown heels
From: Nine West (hecht's, I think)
Purchased: mid-90s
Cost: $25

There is obviously a problem with these. THEY ARE TWO DIFFERENT COLORS! When I first got them, the color difference was subtle. I surmised one pair had been on display and faded a bit. I used to wear them all the time, but would often ask my (female, style-conscious) colleagues if they noticed a difference and was always assured they did not. Now, it's a different story. I liked these shoes, but acquired other brown shoes I liked better, and these have been shoved in the back of my closet for years. The color differential has become extreme. I am torn. Would it polish out? Is it worth it? Should I just get rid of them? I have several pairs of brown shoes that fit this niche that I like much better.

I think I should trash them - I think in a donation pile no one would realize they are a match! Help me out here, what would you do?

Bottom line: awaiting input - leaning towards trashing
