they went back to the original design, exactly what the World Cup 150 was last year is what shell design they are sharing for the line now. The Parafini design according to Lange just didn't perform or fit like the World Cup design. this Design has been around for years and is still a proven winner in and out of the race course.
Guess they figured to go with what has worked in the past and not fix what works!
For the record, they are AWESOME if they fit your feet.
