While I have rarely experienced these as a problem flying in the
west, there was quite a response to my article on the almost perfect hang
gliding shoe, https://ozreport.com/24.098, which decried the mesh tops of my favorite
shoe.

When looking for hang gliding shoes, I'm specifically looking for
gusseted tongues and leather or "waterproof" uppers. Waterproof just indicates a
good foxtail barrier. Anything "ventilated" is definitely a non-starter.

Some unfortunate visiting pilots have had to throw away their running shoes
after flying here. I wish I had pictures. The shoes were so full jammed full of
foxtails, in every possible spot, it would have taken hours to pull them out.
