I have just finished reading the skinhead 1969/70 part of 'Booted and suited' based in Bristol. The stories could have been from anywhere in the country. They certainly applied to my time at that period in North Kent.
Something that brought back memories and something I had completely forgotten about that was mentioned in the early part of the book was that of getting another leather sole put on your Royals even though they were not worn down to give a thicker / chunkier feel and appearance and of course the inclusion of Blakeys front and back for that smart marching sound.
The Royals I have now have a rubber heel but I am sure the ones in 69 had leather heels to match the soles.
Colin your memory is normally on the button whats your recollection?
