[header] How to customize your converse shoes [title] Add studs to the sides of your shoes. [step] Choose the stud shapes you like and then lay them out in the pattern you want before putting them onto the body of the shoe. Grab a stud and then carefully push the stud spikes through the fabric of your shoe (outside to inside). <sep> (A) [substeps] You can buy real studs at most shoe stores, but you can try more and more until you find the perfect size. Another idea is to try slip-and-slide slips. (B) Then spread out any fabric around the stud so that it sits within the shoe and sticks together. [substeps] Adjust how often you put studs into the sides of your shoes as well. (C) Then, lay out the shoe laces (in red or black) and spike them up, overlapping them a bit. [substeps] Don't worry if the lace is not exactly perfect; it can perfectly match the style you are going for. (D) Either use your fingernails or a pair of pliers to secure the stud by folding down the spike ends on the inside of the shoe. Repeat this process for all of the studs.
