In reply to girlymonkey:
That method of lacing is designed to increase comfort around the top of the boot, creating a V shape in the laces to allow for some flex. There is no good reason for it to stop heel lift.
Blisters are caused by moisture, heat and movement. Eliminate these factors to stop the blisters. It's possible that your two pairs of socks are just too warm so try one pair of good quality socks with a good mixture of synthetic and wool materials.
Also the blister under the ball of the foot indicates that your foot is unstable and elongates excessively when you weight it. Denzils suggestion of superfeet might be a winner as they will reduce the volume around your ankle as well as preventing instability in the foot.
As a quick fix though try this lacing technique, it can be quite effective.
Heel Lock
Allowing your heel to lift up and rub against the inside of your boot is a quick path to blisters. A little lift is fine, but more than that and you’ll likely have trouble. The heel lock is a technique designed to lock down your heel and keep it where it belongs—back in the heel cup.
Lace up your boots as you normally would until you reach the bend in the ankle—usually at the end of the eyelets and the start of the open hooks. Make a surgeon’s knot, then slip the lace around the outside of the first hook. But instead of crosshatching the laces, bring them straight up and around the second or top hook. Then cross the laces over and secure them with a surgeon’s knot.
Next, bring the laces back across the boot and thread each lace underneath the vertical lacing between the hooks on either side. Bring the laces back across the boot, give them a good tug to snug up the rear of the boot around your heel (but not too tight), secure with another surgeon’s knot, and tie off.
Hope this helps!
