Query: pretty but unwearable

I bought these in black last year and I was so excited when I opened the box--they are gorgeous!Sadly I was too vain to send them back, because now I have a beautiful shoe that only sits in my closet. They are just too uncomfortable to wear. First, all your weight goes to the forefoot and the straps dig horribly into your toes. Second, the heel slips off your foot in the back, making them difficult to walk in. Third, there is no cushioning in the forefoot nor is there room to place a gel insert (my feet are narrow and yet they are squeezed under the straps in this shoe).I do wear pumps regularly and have a respectable collection, but these must be the most uncomfortable and unbearable ones I own. Strongly recommend that you pass these by!
