Where can I find the “Notify me when available” button?Updated a day ago

To receive a notification as soon as your size is restocked, first click on the sold-out size (the one with a strikethrough) — then the “Notify me when available” button will appear.
You'll find it on the right-hand side of the screen, vertically aligned, as a black bar with white text.

Can’t find the button?
Try refreshing the page or using a desktop device: on mobile or with some adblockers, the button may not appear.
