Generally the process for each drop works the same. SNKRS releases are either LEO which means it’s an instant draw and once you enter the draw you will be in a pending state as you wait to find out if you got the W or L (takes a few minutes). DAN releases on SNKRS mean it’s a 30 minute draw (sometimes less) where Nike takes all entries at once for as long as the draw is open, and then draws winners after the draw closes.
It’s important to note that you can not test how a live release works right now. If you add to cart right now you will see it adds it to your basket like a normal website. This is not how a SNKRS release works.
When you participate in your first SNKRS release you will see how this works live in the moment. It’s nothing complicated so you’ll go from your size automatically being selected to paying in 5-10 seconds.
When you are on a product page for a SNKRS release, you do not need to refresh at the specified launch time. The portion of the page that says “coming soon” should change to your size being automatically select. If this does not happen in 2-3 seconds, then you need to refresh the page.
