Buckles over the foot should be on the first rung or so, and be nice and snug, they really just close the boot. The two upper buckles are a little different. Do the power strap nice and snug under the plastic shell first. Now buckle the second one down. Flip between the two upper buckles, (do a little flexing to help set the heel)until everythin is nice and snug, then buckle over the foot. If you have to buckle the upper buckle all they way, or rebolt to a hole further back, you will probably benefit from tounge padding (check out the Masterfit Eliminator). This can greatly improve ones stance, and ability to flex the boot. If you can barely get the buckles latched, due to a healthy calf, and your lower leg is uncomfortably thrust forward, you should consider having a good bootfitter look at your stance. The fitter might remove padding around your calf, giving you more room, and a more neutral stance. A more commen cure for big calves is to move buckles/ ladders around. This adresses the fit, but not stance. This is all very general, but I hope it helped.
