If your size doesn’t appear in the options on your preferred colour or if the size is disabled (out of stock) it means that we don’t have that colour/size combination available.
We don’t currently allow backorders of the arch support thongs but you are welcome to send us an email letting us know which colour of the thongs with arch suport and the size you weren’t able to buy and we can check to see if we have in our Darwin Warehouse and we can also add this to our list of requests for the next production.
Please note we aren’t always able to produce every size and colour combination, but we appreciate you letting us know what there is demand for.
