Seems to me that the biggest selling point for the gold cup line is gold plated eyelets. Extremely tacky to me, and not worth more than a $5 markup. Although they mark them up $100. (I'll take my gold in coin form not on my shoes.)
Of course, these shoes don't have eyelets so I guess you are paying for $100 for deerskin and memory foam. Unless, the construction is better than their regular line but I doubt it.
