I ordered this product for my wife Marlene.  She wore them for about 45 minutes and has sore places between both her feet between the Great Toe and the first toe.  This is where the leather is wide at the "between the toe" strap.  She took them to a shoe repair shop and the Owner of the shop attempted to fix them by trying to place pressure on the wide place of the strap.  He stated that nothing could be don to repair the issues.  It appears that the strap has the stitching which joins the two parts of the shoe in the exact place where it goes between the toes.  Marlene loves the look of the shoe and how they feel to the other parts of her foot but she will not be able to wear them.  We had thrown the box away plus she had already worn them, otherwise we could have sent them back and maybe tried another design.
