keep leather or go white vibram (crepe)

Newgrass reworked some old Red Wings (v v nicely) with white Vibram soles... had been tempted to do the same to these but after reading The Selvage Yard's last post might not. Pull the trigger?? The ankle top has been oiled here, the rest not... dragged out from a cupboard. Pops' boots, at least 25 years old... older than most of those reading this...
