thanks!! the green velcro was KEY. i moved it lower and now the boots have great ankle flex. i was able to ride all day in flexy comfort!
did your T1s come with instructions? mine did not@!
Between the inner liner and shell, on the "tongue", there's a green velcro'ed on pad. The inside boa goes through this pad. You can move it up and down and it will change the way the boa pulls your heel into the boot. Higher up will make it feel stiffer, lower will make it feel softer (with the boa tightened).
