KATE SPADE Pin-Up Girl Heels platform Red & White Stripe size 9 leather & fabric

Super cute retro Kate Spade heels. The footbed and strap backing appears to be leather, with fabric on top. They’ve only been worn twice but have been stored for quite some time (years, I don’t wear leather any more). It seems the back of one heel has turned a shade darker than the other. I can’t explain it. Maybe a cleaning can help. But being sold as is! Size 9. Fairly comfy for heels. Front platform. Chunky heel. Minimal wear otherwise, no scuffs or scrapes. Just that darkening. 🤷🏻‍♀️
