Many moons ago when I was young and poor some of used the old style football boots, the ones with the moulded soles. We used to saw the studs off and smooth the surface with a surform! You could actually screw the old style shoe plates onto them. They were actually pretty indistinguishable (is that the right word?) from the real thing. I actually wore mine at Herne hill. It brings to mind the fact that a lot of cycling kit is much more easily available and cheaper (relatively) than it was years ago.
