Sidi Vertigo Corsa are all my all-time favorite boots. Fits me perfectly and just the right amount of flexibility. Sadly, now NLA, and after 20k miles the soles on my current pair were not only worn out and partially separated, but also rock hard. Sidi sells replacement soles for not much $, so with a little work I can hopefully get a bit more use out of these.
Heat gun makes short work of removing the original soles. Clean off all the residue and rough up with coarse sandpaper (boot and new soles). Use a good shoe contact cement. Master has all the right nasty solvents. Follow the directions. Cure for a week. Good to go!
