The Purpose of the LACE To tighten the boot on the foot so as to provide a solid transmission of power from the foot to the studs for grip, and to the surfaces used for kicking. It must maintain this throughout the game. The method of lacing affects the tension required in the lace to achieve these aims.
The Up and Under One end of the lace is inserted though the lowest hole on the outside of the boot (the Left hand side for the Left boot) and fed behind to the opposite side hole. The lace ends are then matched for length. The one end is then inserted through the opposite lowest available hole from behind. The other end is then inserted by the same method. This process is repeated until the top holes are reached.

The Chris Cross One end of the lace is inserted though the lowest hole on the outside of the boot (the Left hand side for the Left boot) and fed behind to the opposite side hole. The lace ends are then matched for length. The one end is then inserted through the opposite lowest available hole from the front. The other end is then inserted by the same method. The one end is then inserted through the opposite lowest available hole from the behind. The other end is then inserted by the same method. This process is repeated until the top holes are reached.

The Ladder and Slide One end of the lace is inserted though the lowest hole on the outside of the boot (the Left hand side for the Left boot) and fed behind to the uppermost opposite side hole. The other end is then inserted through the other lowest hole and fed behind to the first free opposite side hole. This process is repeated until the top hole is reached.

The Ladder and Step One end of the lace is inserted though the lowest hole on the outside of the boot (the Left hand side for the Left boot) and fed behind to the uppermost opposite side hole. The other end is then inserted through the other lowest hole and fed behind to the next same side hole. Then it crosses to the other side over the top. This process is repeated until the top hole is reached.

Variations Their are three other main variants of these methods:- both boots laced identically, as in the right hand boot, as in the left hand boot, and the boots threaded as the mirror image of the above methods. Other variations are a combination of the above over methods used in different regions of the boot.
I am trying to compile data about boots used to play Rugby. This data will be published here in the WWW as it becomes available.
