So disappointed!  I bought these for a trip to Ireland at the last minute.  While they definitely are a stylish sneaker, they fall short in a number of areas.  First, the odor from the materials is overwhelmingly toxic.  I don't know if I can stand the odor on a 7 hour flight.  They smell absolutely toxic.  Second beware that they are extremely narrow, so if you have a wide foot don't bother.  Fortunately, I have a narrow foot.  They are also short lengthwise.  I ordered an half-size up, but should have ordered a whole size up.  Last, there is no arch support.  The heel actually feels a little elevated, so they have a strange fit.  I resolved this issue with some small arch inserts.  I wanted to love these, but I'm afraid they will have to go back.
