Are they aluminum? I have the ones with the card suite. They are nive stirrups but hugely wide across, for a big foot. I wear womens sz 5.5-6 boots and I think the stirrups are too wide for me. They are very flat across the bottom, as well.
I polished mine with Mother's Mag and Aluminum Polish. It takes the rough edges off the engraving and makes the stirrups look like sterling silver, almost.
