10 Everyday Objects You Didn’t Know Had Hidden Features

4. The Purpose of the Extra Shoelace Hole

Many athletic shoes come with an extra shoelace hole near the top, often ignored by users. This additional hole is designed to create a "heel lock" or "lace lock," providing extra support and preventing blisters. By threading the laces through these holes, wearers can secure their feet more snugly, reducing slippage and enhancing stability. This feature is particularly beneficial for runners and hikers, who require optimal foot support. The presence of this extra hole exemplifies how subtle design choices can significantly impact comfort and performance. Understanding and utilizing this feature can transform a standard pair of shoes into a customized fit, tailored to individual needs.
