So i went to a bootfitter and they fitted me for a pair of Krypton Pros 28.5. I couldnt get them that day, and when i went back they were sold. I found a pair of new Krypton Rampages 28.5 for a good price and i was wondering if it would be a good idea to buy them. Whats the flex difference? and is there any difference in the shape of the foot.
