At some point or another, we've all noticed that extra hole at the top of our sneakers.
And you've probably thought: "Hmm that's a bit random!"
But it turns out there's actually a legit reason why that extra hole exists - although not many of us use it!
Believe it or not, lacing your shoes through that hole helps to create an extra level of snugness, which stops your feet from slipping forward inside the shoe.
Thus, reducing the risk of getting blisters!
