> I can recommend the general principle much, if you enjoy barefeet running, but not cutting your feet open.
I can also recommend Vibram five finger shoes for swimming where there are rocks or sharp shells or corals. They basically work like wetsuit feet with a great grip - and helps avoiding falls and cuts. Works both for summer and winter in my experience.
Well, I would love the vibrams to be custom cut to my feet, as well, because my toes are not standard size either (no feet truly is).
Sometimes in fact, 2 toes get into one, but it is actually not too uncomfortable, so maybe it would still work for you? There are many different models, some would probably be better suited as they are more flexible and wider, but I have no idea about the current models.

Ed: or just for wading/ crossing streams.
