Lock Lacing

Not a lacing method as much as a technique for creating a super-tight finish. It's often recommended to help reduce heel slippage in running or climbing shoes. Also referred to as "Lace Locks", "Heel Locks" or "Runner's Tie".

Lacing Technique 1 - High Lock:

• Lace the shoe up to the second-from-top eyelets using any lacing method (eg. Criss Cross Lacing is shown here).

• The ends run straight up on the outside and in through the top eyelets.

• The ends are crossed, then each end is fed under the vertical section on the opposite side.

• The ends are returned to the middle for tying, pulling the vertical sections inwards.

• Lock Lacing is also used by rock climbers to prevent any movement or twisting of the shoe under the stresses of climbing as well as by speed skaters to give maximum ankle support.

• Although Criss Cross Lacing is shown in these examples, and is probably the most common method used, the shoe can be laced with almost any lacing method. In fact, as pointed out by Kyle B., Ladder Lacing naturally ends with a High Lace Lock.

• Lock Lacing also creates more friction, which should help prevent the knot coming loose, especially with slippery synthetic shoelaces or if you are unknowingly using a Granny Knot. Replacing slippery shoelaces or changing your Shoelace Knot are better alternatives.

Lock Lacing Theory:

Many shoe stores recommend Lock Lacing techniques to help prevent heel slippage, particularly when running downhill, and many people swear by them. In fact, many sports shoes have twin eyelets at the top to suit Lock Lacing. So what's behind the "magic"?

The answer is simple leverage. While pulling the lacing tight, the upper straight sections get pulled into a triangular shape, acting like "pulleys" to provide even greater tightening.

When shopping for shoes, don't be too impressed by a savvy shoe salesperson using Lock Lacing to get a slightly better fit from an unsuitable pair of shoes! If you've found some shoes that meet all of your other needs with the exception of a bit of heel slippage, then Lock Lacing could be the ideal solution. However, if you suffer from a fair bit of heel slippage, Lock Lacing will only help so much, and it could be wiser to seek some better fitting shoes.
