A zipper broke on my half chaps so I'm in need of another pair. Problem? I have a 10.5" calf (yes, widest part), BUT I fit the height for around a ladies small (16"). My current pair was from a local tack store, no name brand. And there aren't any more. Anyone know of something that might fit? My tall boots are an Ariat regular and they fit rather well, maybe a tad tall but not enough to be a problem, and a tad wide, but not enough to need a slim.
