I have Cabela's brand lightweight breathable waders. They are waist high, just like a pair of pants. Very comfortable and have had them for 2 years now. They where used hard trout fishing PA streams and have seen some time surf fishing. No problems with these yet. Mine are stocking foot, not sure if they have them in boot foot. They weren't really too expensive, i think around $120 when I bought them. I see they are closer to $140 now. Here is the link
