Also, for what it's worth, these are the men's version of the boots that I have: Paddock Boots Heritage III Zip - Ariat
I love them, and they are super comfortable. I've had the same pair for the past four years or so, and they're just starting to develop cracks. My last pair lasted about the same amount of time, usually with riding at least one horse 5 days/week. Sometimes less, often more.
My half chaps are about 10 years old, so they don't manufacture ones exactly like them anymore. However, these look to be a comparable model: Half Chaps All Around Chap III - Ariat
Like I've said, they've lasted about 10 years for me. The elastic strap that goes under the foot has finally started to fail (a few of the bands have popped, but I guess the rest is on its way out) so I think I'll be investing in a new pair soon. Can't complain about the comfort, and they get the job done! There are plenty of other options out there, but I'd get something nice if you're planning on sticking with riding for any length of time. I bought a cheap pair of really thin stretchy washable half chaps for throwing over my jeans when going out for a trail ride or something, and they showed a LOT of wear for only being used for those occasions and a couple of "real" rides. The zipper came off of one of them the first time I put it in the washer after a year or two and only 20 rides or so.
