Size 8.5 Strappy High Heels (+/- 10 miles from Sunnyvale)

Looking for women's size 8.5 (regular to wide width) strappy high heels, preferably 3-4" high, in good condition. Any color or style, including platform heels, is fine.

I'm on the board of a nonprofit, and we're having a fundraising fashion show. All the board members have been invited to open the show by walking the runway, and I'm actually going to do it! Need heels with ankle or other straps that will stay securely on my feet (slip-on pumps aren't a good fit). If you have a pair collecting dust that you'd be happy to rehome, I'd be very grateful. If they don't fit (I'll try it at pickup point), I will not take it home but will let you know. Thank you!
