In the absence of any other replies, I've got to tell you that I found and ordered a pair of hip boots at a cost of $110. Admittedly, they exceeded your $100 limit and are made by Caddis. I thought Caddis was a reputable manufacturer. If I had seen them in a store, I would have laughed and walked on by. Sorry, but since I immediately returned them, I cannot recommend them for purchase. Good luck finding a decent pair of hip boots anywhere near your price range.
