Nope, the brown shoe has less slip than the black shoe.
Perhaps it's a different brown material but if I take the description of the XP clutch shoe (6587XP) from the Centax I / II clutch shoes, it reads like this;
"This black centax clutch shoe is made from a new material that gives you more ‘punch’ on acceleration. Although, due to the nature of the material used on the XP (xtra performance) clutch shoe, you sacrifice longevity, the extra power gained is worth it."
I would interpret that the material used on the XP shoes are softer and hence have more grabbing effect on the clutchbell... But of course, I may be wrong again !
