I had foot surgery on both my left and right foot to fix my bunions. The result of the surgery is that only certain styles of shoes are comfortable to wear (read that as no spike heals, no strappy sandals, no flats). I am truly in love with Bionica shoes. Besides my foot issues, I am vertically challenged and thoroughly appreciate the height that these (and other styles) have. They are a bit pricy, but seem to be of excellent quality.
