I wear Ariat paddocks and matching half chaps that are normal leather, but with a suede inside patch. They're nice and grippy and keep my leg in place pretty darn well. They are also slightly padded and have nice big zippers and an elastic panel by the zipper which means I can get them tight enough that they mold to my leg.
They also look very much like a tall boot: Half Chaps Classic III - Ariat
Back when I was in college, I wore cheap ($35) half chaps -- the full suede kind that had three velcro tabs on the side -- and those actually did a pretty good job for the price. I didn't care if they got dirty, I'd ball them up and throw them in my grooming bucket and were just fine the next time I came out to ride.
You might want to get some of the cheap half chaps and try them out before committing to anything more expensive.
Right now, I've logged maybe ... 40-50 hours of riding in my half chaps and they show virtually no signs of wear and tear.
