Why knot laces

It's also great for people who are very active on their feet, such as when playing serious sports, mountain climbing or even dancing, as well as for yachties whose boat shoes are constantly getting wet. Please see my Granny Knot page that discusses this in detail. This page last updated: Oct All rights reserved. Website created by Ian Fieggen aka. Step 3: Cross the right blue loop over the left yellow loop so that the blue loop sits in front and is now the left loop.

Step 4: The yellow loop is now the right loop. Step 5: At the same time, begin to wrap the left blue loop around the back. Step 6: Feed both ends of the loops through the hole in the middle.

Step 7: Now, simply pull the loops to tighten the knot. Finished Knot Gallery The finished Ian's Secure Shoelace Knot should be a tight, closed knot with a symmetrical double wrap around the middle, as compared to the single wrap of simpler shoelace knots. Fourth of five different lacing methods on Guy's shoes.

Finished off with Ian's Secure Shoelace Knots. Lacing is finished off with Ian's Secure Shoelace Knots. The knot itself is under pressure too. The videos showed as the shoelaces bounce up and down with each footfall, the main knot begins to deform. Once the knot opens sufficiently, then the free end of the lace, which is being tugged by inertia, begins to slip out. As the leg is swung backwards to impact the ground, the inertia of the free ends and loops pull open the center of the knot.

If the free end and loops are approximately the same length, these forces will be comparable. If the knot center is tightened, frictional forces will somewhat ameliorate the inertial force imbalance.

Repeated impact causes the center of the knot to incrementally loosen which reduces frictional effects and magnifies the effects of the inertial imbalance between the free ends and loops. The team built a robotic pendulum to examine the math on a deeper level. As the length of the loose end increases, so too does its weight relative to the other strand. This trend adds to the inertial forces, until total shoelace failure. Moreover, the bows of your shoelace are not exempt for this flaw.

A pendulum experiment was used to study the effects of impact and lace dynamics on a knot. When the team added little weights — ranging from 1 to 3 grams — to the free ends of the laces, they found heavier weights caused the shoelace knots to fail at a higher rate. Though the amount of time before a failure varied, the researchers argued these basic knots will eventually slack off.

Also, you can try tying a tighter knot, but even those may break your heart. Robert explores how these building blocks can be combined to produce a wide variety of exciting projects which will provide enjoyment for many years to come. A complete list of the tools and materials needed to complete the project are listed.

Robert elaborates on knot tying sills which will become important building blocks for use in many other fancy knotting projects. Robert introduces you to this famous nautical knot.
