Do I just need the dye or do I have to deal with all this stuff with sodium sulphate and sodium carbonate? Also, does anyone have measurements for those black Spurrs on Farinelli's? Alternatively, do Spurr Boot Rigids or Nudie Regular Alfs come in black/grey? I heard that you could just RIT dye it for a couple of minutes and you'd be fine. With the measurements, why not just email Farinelli's?
