Most of us have been wearing sneakers our whole lives, but have never actually known what that peculiar extra shoelace hole is for.
This genius video tip explains just what the seemingly useless hole is for, and will change your life if you suffer from painful heel blisters.
Most people don’t realize it, but the extra shoelace hole near the ankle on the sneaker is actually for a shoe-tying method call the ‘lace lock’/’heel lock.’

Using the extra hole ensures the heel of the foot remains secure, and prevents chafing and blistering.
Once you create loops on both sides of the shoe, cinch the laces down, and pull the end of the laces down. Simply tie a normal knot to lock the foot in place.

Watch the entire video below to see exactly how to tie a ‘heel lock.’
