My tall boots cost too much money for me to wear them for everyday use. Plus, although they are great in the saddle, when I am grooming and doing other chores, they are uncomfortable because they cut into the back of my knee.
Paddock boots and half chaps are comfortable and more convenient. I don't have to worry about keeping them shiny and if I get them wet while rinsing off the horse, I just wipe them off and put them away. The half chaps, which are full leather, take no real additional care, and I occasionally (every couple months or so) clean and mink oil the paddock boots to protect them from the elemets.
Extra bonus - the half chaps are more grippy than the tall boots.
