Harley-Davidson Black Engineer Boots

This was purchased about 10 years ago for my wife.
They haven't been worn much, so the soles and outer leather are still in good condition, but the inner leather has deteriorated.
The size can be confirmed in the photos, but it says USA 6, so it's likely a Japanese size 23.

Since these are old, please understand that they are non-refundable and non-returnable.
