I bought these shoes hoping that it will help to prevent any lower back discomfort that I sometimes get with other shoes when I work.  I am very disappointing with how they feel and the lack of comfort. I really want to love them, my friends love them, but I just have not been able to feel comfortable and secure on them.  I feel wobbly when walking, and especially on padded mats that we have at my work.  I almost sprained my ankle on these shoes, so understandably I refuse to wear them now.  I gave these shoes one star for the only reason that they make me taller then I am, a welcoming feature to a 5.4 statue.
