Today at a running shop we had discussion that the new Boston Classic {dark color} was heavier then last years Boston Classic {white model}...Some disagreed..saying Adidas would never change the Boston Classic...the other Classic fans also said the dark Boston didnt have as much arch support...so we weighed the 2 Boston Classics...both size 11.5....dark was heavier 13.4 ounces compared to 12.6 for white..any reason why Adidas changed the shoe..??..any thoughts..??..thanks
