the rampages go anywhere from a 8-15 on dalbellos scale. In a much more simplified sense, there right in the middle between the 1080 and the pro model. Stiffer then the 1080 but a tad softer then the pro model. The only other difference comes on the fact on how the boot flexs much more smoothly and evenly then a 4 buckle boot. So to get the same amount of reponse from the boot you dont need it to be as stiff. Sickest boot ive ever used
