Yeah I check that site sometimes to compare information I get from other sources. According their site ankle articulation - "usually tells how well the ankle retains its flex"
I take it some boots restrict ankle movement/flex more than others.
Interesting lol. I was also recommended to check out the 32 TM-Two's, 32 Lashed, Deelux ID and obviously Burton stuff..
I'm looking for around the 6-7 stiffness so I can take them into the park as well as have that response I need for the glad type terrain. It sounds like you might be in a similar boat so figured I would give those suggestions to you as well.
