As far as the sagittal movement...I would think that might be due to the shape of the lace eyelets. The mako seem to be a C shape vs the more L or vertical as say to a vapor. It seems that with a C shape lace pattern your high ankle/shin would contact the top lace earlier when forward flexing causing you to need more weight and force into the boot earlier. That's what 55 flex concept does with skates. They seem to become more aggressively forward "L" shaped in the lacing pattern. For those that skate with the mako how is the feel of forward flex vs other boots worn?
