for wet footing in the canoe I wear NRS Attack Shoes which are neoprene booties with an insole that provides arch support and an outer sole that refuses to slip on wet rocks. For dry footing I wear Chota breatables. As soon as I disembark at the landing I switch to high cut hiking shoes that have my orthotic arch supports. This gives my feet a rest while around the landing and around camp, and keeps my feet from hurting on the portage or while hiking. The high cut hikers I have are Merrill and HiTech, either pair only weighs 2.5 pounds. I keep them in a lightweight dry bag attached to the outside of my pack. Sometimes I bring my Keen Newport sandals with the toe cups for lounging around camp. They pick up gravel between the foot and footbed if worn in the water. Wearing wool socks with the sandals helps, but not as effective as the NRS Attack shoes. I tie the NRS Attack river shoes to a canoe thwart or my pfd when I'm not wearing them. I also use the river shoes for swimming where it is rocky or mucky. I've never had sand or grit get inside. They are lightweight and supportive enough for short portages unless the terrain is terrible, at which point dedicated hikers are a necessity in my opinion. The attack shoes have a leather patch on both sides of the ankle to help prevent bruising when wading in rocks. The soles are narrow so they don't tend to wedge in rocks the way bulky sandals or hiking boots do.
