Thanks for all the info!
I was looking into getting half chaps because I'm riding English. I have Western boots because they were a 'cheap' alternative to expensive riding boots. The boots I have go up to the middle of my calf. The first time I trotted in the English saddle I got some reddness and bruising on my upper calf from the stirrup leathers.
Since then I have been using leg warmers. Not a big deal to me but I thought if half chaps helped performance I should look into getting some. It's good to know that they won't work with all western boots. Better to know that now then to go in to a place and look like an idiot. I'm sorry but I don't know the difference between boots.
These are the boots I have: Here
Duck, thank you! It is true that while I am horseback I don't really pay attention to how sweaty I am. It's only after I get off that I notice I'm dripping sweat lol.
Lilac, yep! That's the place lol, that awkward border area!
