In trying out a couple pairs of Classics, I discovered that there is a BIG difference in the rubber soles of Mauve vs. Black classic! I was looking at 2 pairs of W38. the black had much harder/structured soles, and the mauve is considerably softer (e.g. you can very easily squeeze and fold the bottom of the toes sideways. the Black soles, as well as the soles of my lichen sprint, are much harder/tougher.)
Has anyone else noticed this about Mauve vs. black soles, or perhaps it's a common difference b/w darker vs. lighter colored soles??
