Today adidas will start to introduce the option to buy products directly through Twitter. adidas Originals has tweeted that a restock of the black and grey Tubular Dooms will be available through Twitter on March 28th. Make sure to follow this account for updates on this release as well as future releases that may go directly through Twitter.
When the product is live, it will have a Buy Now button and you will be able to select size and color. First time purchasers will be able to enter their payment information through Twitter. Once the purchase is made, it will show up in Order History under the Twitter settings. Email confirmations will also be sent out to confirm the purchase. Good luck!
Update: the Tubular Dooms went live on the main site around 7:15pm EST in the black and grey colors, sizes 4-14 for $160. A buy now tweet went up briefly before the links to purchase on the main site.
