They don't work any more. They're taken off their page.
But here: https://www.dtlr.com/product.html?productVersionId=35c2a7E2-a746-47cd-8d5e-c250d37953d2
Since DTLR took down the link to the product page, is it still possible to find the shoe through their website? I'm assuming that the link will just go live whenever they release or they might create a new link altogether.
