You love your favourite pair of shoes -- the ones that fasten shut with Velcro. In fact, you wear them everywhere. Lately, you've noticed that once you've fastened them snugly, the strap loosens before you've even taken a couple steps. Worse, it looks like the Velcro is about to fall off. You can fix the Velcro on your shoes with items you already have at home. With a little patience, your favourite shoes will be ready to wear in no time.
Clean the Velcro. Often, the Velcro won't "catch" anymore because it is matted down with hair and dirt. Use a hand sewing needle to gently "pick out" all the foreign matter on the hook side of the Velcro. Clean it out row by row to make sure you get as much as possible. If the fuzzy side seems flat or dirty, scrub it gently with an old toothbrush and hand or dish soap. Allow it to dry thoroughly before wearing.
Reattach loose Velcro. If the Velcro on your favourite shoes won't work because it is falling off, you will need to sew or glue it back on. Thread your needle with thread that matches the colour of the Velcro and hand-stitch back in place. Wear a metal thimble as you sew; stitching through Velcro and shoe leather or vinyl can be difficult, and pushing the needle with the thimble makes it easier. You can also glue the Velcro with a drop of glue. Apply the glue and press the Velcro into place. Do not get any glue on your fingers. Allow the glue to dry for at least thirty minutes before wearing.
Replace the Velcro. If the Velcro hooks are too badly broken to attach to the fuzzy side anymore, or if the fuzzy side is too dirty and matted to respond to cleaning, replace the Velcro on your favourite shoes. Use Velcro tabs close to the colour of the shoe and attach using either method in step 2.
