I'm guessing you have them. I have them at 80, I am 5'11" 155lb and I like them fine. I don't find them that soft really. Put the inserts in for each flex and see what you like. Simple as that.
Oh sorry, I misunderstood. They might have the flex adjustment on the inside of the cuff. Take the liner out and see if it's there. The tongues are interchangeable too.
