I've only ever had some rubberised waders which have had it. And so I've been looking into getting some breathables but seem to be lacking some gen. All the sites I've looked at seem to be selling/packaging these with separate boots, seemingly with a choice (felt/cleated soles). Do you buy the top bit (stocking foot) of the waders and then buy some boots? These must then attach in some magical, waterproof way? How? The only breathables I've seen are my mates where the boots are permanently attached. Sorry if this seems a bit basic to some but I've never come across these and am wondering how they work...
