During the summer, I usually use old tennis shoes, etc. I seem to recall that much use of them wading and they would fall apart. I'm told the new design water shoes hold up well with continued use.
Got some Teva Omnium water soles designed for river guides. And some SealSkinz waterproof socks. I kinda like the idea of keeping my feet as warm as possible while wading in those back country lakes. They are far lighter than packing any of my waders.
So, we shall see. E
