Ive had the pads for a few weeks and am super happy so far. Make sure the copper is nice and clean (shiny). The back straps on these shoes are attached in such a way that they can bow out a relatively considerable distance from the side of the shoe (see photos for reference). Super comfy shoes. I shared these packets with my 3 daughters whom have different styles ?? They can be used as a choker, waist beads and an anklet or bracelet! honestly they were a royal p. I went ahead and gave it 3 stars because they did look well constructedThey sat in my closet unused until I found my dog chewing them up. Before installing, use a sharp razor to gently cut through the thin 3mm foam, which is just behind a thin layer of nylon. Great cheap option to bring back my old batwolfs. Stylish, too.
