Yes, our design is perfect for all foot types. We recommend choosing half a size up for wider feet.
We have actually done extensive width testing and surveying of thousands of women around Australia allowing us to have a great understanding of how our shoes fit and the types of feet they suit.
You may have a small degree of overhang along the outside of the foot, however, this is certainly no more (and likely less) than what you would expect in other footwear. The most important thing is the sandals are comfortable and the orthotic sits in the correct position on the foot.
