Just talked to a rep on adidas.com... the only between the new core blacks and the old ones are that the newer ones have a slightly lower heel to toe drop and weighs 0.1 ounces lesst. Also the color of the torsion is orange instead of yellow.
Just ordered a pair :D
Anyone know if this site is legit?
