While most runners, walkers and hikers likely think nothing of them, the shoestring holes on the top of your sneakers are there for a reason!
These top two eyelets are meant to lock the foot and ankle toward the back of the shoe to prevent blisters along the toenails. Especially when people run or walk downhill, the foot tends to slide forward creating these blisters. While most people see this as a sign they need new shoes, the issue may be simply that the shoes they are currently using aren’t tied properly through these eyelets.
The first step is to find a pair of quality athletic shoes. Reputable running stores can not only provide this for you, but many staff members at such stores also have the training and expertise to show you how to lace your shoes correctly. This is important year-round, but especially in the summer when feet sweat and swell more, increasing the risk of blisters.
