Double Helix Lacing
Also referred to as "Spiralacing", this patented method has the laces angled one way on the outside and the other
way on the inside. The resulting double helix reduces friction and allows faster, easier lacing.

• Begin straight across the bottom (grey section). Note the unusual path: Feed the left end
out through the bottom-left eyelet. Feed the right end
in through the bottom-right eyelet.
• At each eyelet pair, the right end runs diagonally on the inside and out the next higher eyelet on the
left, while the left end runs diagonally on the outside and in through the next higher eyelet on the right.
Repeat until lacing is completed.
Simple to lace
The left and right shoes can be laced in reverse (mirror image) so as to end up with a symmetrical look.
Double Helix Lacing Theory:
This method was invented and patented by
for faster and easier lacing of shoes and boots. The idea is that there is less friction between
the laces and the edges of the shoe flaps, plus negligible contact between overlapping laces, reducing friction
In addition, as illustrated in Monte's patent, groups of two adjacent laces can be pulled simultaneously (see
animation at right).
All these factors combine to make tightening and loosening easier, especially on tall boots with many eyelets.
Sports / Military Advice:
Like various straight lacing methods, Double Helix Lacing has an additional benefit for sporting or military use:
The upper sections of shoelace can be quickly cut through with a knife or scissors in order to more easily remove
a boot from a broken, sprained or otherwise injured ankle or foot.
Note that most military forces have regulations for just about everything, so I'd recommend that military personnel
check before they adopt this, or any other, possible non-regulation lacing method!
