The first pair shown below are made by Lucchese, are 13" tall, and have standard 1-1/4" cowboy heels. They are extremely comfortable, and can be worn all the time and walk for miles, if necessary. These are the pair of Black Dress Cowboy Boots that I currently wear most often.
The second and third pairs below are made by Dan Post. Pair #3 are about 30 years old, and were my first pair of "Sunday go-to-meetin' dress Cowboy Boots. As you will see, they've needed some cleaning. The third pair have an excellent shine on them and have rejoined the boots in my bedroom closet to be worn more often.
These Boots are great with a suit as with a pair of denim jeans.
