Vintage red western boots are like any other vintage cowboy boot, hard to find!
As with any collectible an interesting history can drive up the value and scarcity. Although you can wear your collection!
When looking for a pair of vintage red cowgirl boots make sure that the leather is not
too brittle and dried out. Expect some scuffs but as long as they are not on the toe then you are probably ok. Always check out the inside for any specific boot maker markings. Who knows you might get lucky and find a pair made by a famous boot maker like Lucchese.
You can expect a wide range of prices on vintage cowgirl boots. An estate sale find can be as little as $10 where an auction on one of the auction sites can bring as much as $1000.
