We can email you a restock notice. Simply click on the size of the out-of-stock item. A drop-down menu will appear where you can select the size you need and your email. You will be notified when you can order it! We also have a restock page that is updated to let you know a general timeframe for when the shoes will be restocked. You can see that here Restock Schedule
If there is a note on the product page that an item is discontinued, then we will not be restocking it. You can check for availability at other retailers by searching the internet by the name of the shoe. You may be able to find it at one of our authorized retailers.
