Full tilt flex compaiasin?

8 or 9 flex tongue will get you there.

+k thanks

Jesus that means FT's are soft. Seth Morrison's boot is a 100-110 flex? Are you sure?

Here's the best breakdown:
#10 tongue = about a 140 traditional flex
#8 tongue = about a 125/130
#6 tongue = about a 100/110
#4 tongue = about 80

As someone earlier noted, the liners themselves add to the boot's overall stiffness too, so if you put a #10 tongue on a Classic, it won't be quite as stiff as an out of the box Seth boot because the liner of the Seth is way stiffer and firmer. Bear in mind that the whole point of FT's 3-piece design is to provide an unimpeded flex pattern, so a #10/140 tongue might feel softer only because it's actually flexing the way it should.

Your a little off in your conversion there. A 10 is no where near a140. Take about 20 off all those and your about right. But to op yeah full tilts are pretty soft and often need the shells riveting to stiffen them up.

I think its like 3-5 is about 80-90, 6-8 is like 90-110, and 9-10 is like 120
