I use boot hip waders right now, as I use them both for fishing and field hunting for pheasant. Were I only to use them for fishing I'd get the felt soles or stocking foot, but slogging through the muddy fields makes the boot type worthwhile.
Hip waders weight less, and I use the thinner lite styles made with polyester/rubber other than neoprene or canvas, simply due to temperature or weight. They are also much cheaper which is good, but won't last as long as neoprene, which is bad. You need to match your waders to how you will use them. I need the lower weight, moving through mud will wear someone out quicker than just using them in water.
Good neoprene can last for years, even decades if cared for. Rubber or nylon/rubber and polyester/rubber will last 1-2-3 seasons at most usually.
There are some breathable types of both the hip style and chest waders, you may want to look into those as they should be cooler. If you do get neoprene, they come in 3.5mm and 5mm thickness, you'll want the thinner ones.
The biggest brand is
Hodgman, they also make Sterns and Mad Dog brands. Another brand is
Allen.
Check them all out, you can usually find representative prices on Amazon for most. I did buy my last pair locally for less though, even with tax. Good luck.
