Originally bought from another eBay seller and they're lovely boots, but sadly as a size 3 they're far too roomy for me. I'd say they're definitely more of a size 4. Or maybe it's because of the wide fit. The original seller's description is below:

These boots are size 3.5 wide fit .

I am size 4 and they fit me well.
