In my collection of photo gear that looked handy when I bought it, are several

to work, even with their hotshoe contacts shorted out?

You need to insert a thin piece of mylar or similar to prevent shorting. When I asked about this very thing a couple of years ago, somebody suggested that 35mm film could be used for that.

The better coldshoes are either insulated or leave a gap under the flash shoe to prevent shorting.
