Hiking Boot Weight Info Please

I was watching a clip on youtube and the subject of lightweight hiking shoes was discussed and the presenter stated that he had ditched his full height and heavy weight hiking boots in favor of low cut trail running shoes or similiar because of his thoughts that a gram on the feet is a tonne on the back(I may be exaggerating a bit but I hope you get the point.
My dilemma is that I have 2 pairs of boots,one being a pair of hiking boots weighing 1.6KG and the other being a pair of wading boots that are designed for being constantly wet and able to stand up to rigours of walking/fishing upstream all day weighing in at 2.8KG.I have a walk coming up in a months time and up until this morning all my training walks have been done in the hiking boots as I didn't want to wear out the souls on my wading boots.I don't want to take in 2 pairs of boots so am undecided whether
to wear the hiking boots and face a slip or 2 on the rocky river beds or hike in the wading boots which are much heavier but very suitable for the fishing.
My main purpose of my trip is the fishing with the hiking being used for the isolation and being able to fish new water for me.
It is too late to get a lighter pair of wading boots so any thoughts on my dilemma or the effect of boot weight would be greatly appreciated please.
