I am 45, and due to over-pronation diagnosed in my early 20s, I have been required to wear prescription orthotics, but as of 10 years ago  I discovered Vionic shoes with built-in correction which I buy exclusively. I absolutely LOVE Vionic shoes, sandals, boots, slippers, and sneakers but unfortunately I have experienced several pairs of their shoes with defects over the years.

Initially I bought this shoe in black and due to the perfect  fit , the comfort, and nice amount of correction, I then bought a second color in my usual Vionic size (10M) in the pewter. With this  second pair, the left shoe fit well, but oddly the right shoe was very tight. (What?)  I did not want to give up since it is a cute shoe with necessary correction I require, so I tried again and bought another pair. With pair #3, both shoes fit this time, HOWEVER, the left shoe was clearly defective. This is hard to explain, but in the front of the shoe there is an uncomfortable "mass" of extra material sewn under the footbed near the toe box which feels like there is a large rock is under my toes!  The rock hard "mass" of extra material is impossible to ignore with each step, and I can see it too. It does not show that well in photos as it does in person, but I will attach as photo. I will definitely call Vionic to report the fact that I received two different defe active pairs of the Maris wedge sandal. Of course I am grateful that the first pair worked well.
