Sell them on ebay. I have sold a ton of bike stuff and have done very well.
Painful feet can really ruin your day. Cut your loses and get shoes that fit.

I have big feet (10.5) and had to try on Shimano men's shoes to check the fit. They felt a bit tighter than I wanted but the charts said I needed a 43 so I had them order the women's version in 43 anyway. Call it vanity. I was nervous that they would be even tighter but they were looser! I love them.

I live in a house of men so my only outlet for feminine and pink is me. I always opt for the girlie version for personal items. If it is available in pink, that is always my choice. I get more compliments on my pink MacBook case.

Hopefully I will be blessed with grand-daughters someday!
