The insoles of women's shoes are often uncomfortably slippery. If you want to end the slipping-and-sliding, try this 10-minute hack for a more stable pair of heels.
Instructables user kazmataz recommends using fabric that's strong, at least the size of your feet and, obviously, not too silky or thin. Cloth that's too thick could also cause problems, altering the fit of the shoe. The fabric she used has some texture and about the thickness of a cotton T-shirt.
Once you've got your fabric, making your no-slip inserts couldn't be easier: trace your foot and cut out the outline, then use spray adhesive to apply it to your insole. Voila! No more slipping.
