Have you seen the shoelace holes beyond the last holes you usually use for tying them the laces up? Well, they aren’t there just for the sake of style.
People get blisters on their feet while walking on a tough terrain. The main reasons attributed to this irritating skin problem are sensitive skin and the constant rubbing of feet with the fabric of the shoe. These blisters can be avoided easily by tying the extra lace holes in the form of a lace lock or a heel lock.
