these flats are not true to size. i wear shoes between a 8 to 8 1/2. i got an 8 1/2 thinking i was being safe..no cigar. i need a 9. i will be returning them. i agree with a preivious review that they are not very comfortable. i expect to be able to wear flats for hours but the material is hard & inflexible so i can predict that they will have a short span of time before the complaints start :( i bought the grey bc i really needed a flat grey shoe in my closet & i couldn't beat the price. i guess u get what u pay for!
