No matter how many times we tie our shoelaces, they always seem to come undone on their own accord.
Scientific experts from the University of California have now finally uncovered the reason as to why.
The discovery concluded that the repeated impact of a shoe to the floor is the cause.
As expected, the study also found that the laces go into a whipping motion when our legs swing, causing them to slip.
There are two common ways to tie a shoelace identified by the study.
One can hold it together longer but still fall apart eventually while the other would come undone shortly after being tied together.
Professor Oliver O’Reilly, who helped conduct the study said, “We still don’t understand why there is a fundamental mechanical difference between those knots.”
Although no official solution researchers found more tightly tied laces could withstand more impact and leg swings in a day.
