Many, many years ago, I used motorcycle innertubes.
Today I have converted to Lewis boots, but I always carry an innertube and some duct tape in my vest, in case a dog throws a boot. I have only lost one Lewis boot and that was because it was put on when the rubber was wet, and the boot pulled off the boot.
The dogs never seem to notice them in the field. It takes less than 5 minutes to boot em. Even if burrs are not too bad, I really notice a difference in how the dog runs the second day.
