Very interesting. I travel to Taiwan, HK, Shenzhen regularly, soaked couple of my shoes from monsoon several times, and none of them rust.Did the rust appear at the toe plates? Or the brass coated screws?
Nails are useless against toe wear since the wear starts at the toe tip edge. And no one can put nails at the toe tip edge.I have a pair of sc shoes with sunken toe plates. No idea if it rusted or not but it resolved fine. My couple years old Vass loafer thatve survived couple monsoon season soaking wet did not rust at all.The nail heads wears down fast for the shorter toe shoes.
It's a huge myth that GY or hand welter construction is water proof or water resistant.It is not much more water resistant than channeled Blake stitches shoes.Water simply sipped into insole from outsole.
ETF can also reverse split as well, see most volatility ETFs.Remember, ETF is at least an derivative from its underlying. Sometimes it's a second derivative whose underlying is an derivative itself.Caveat emptor. What you buy is not what you see for ETF.
