If I had to guess, Vietnam, which has a very large shoe-making capability.
I sullied my brower history and actually went on the site to try and find out. Needless to say, the whole thing is a con on the feeble-minded.
There’s no info anywhere about where they are manufactured, materials, specs, anything whatsoever beyond a picture (which I think is illegal). The shoes won’t even ship until July/ August. There’s also no actual representation of what they even look like. The site, in multiple places, says “only an illustration and not necessarily representative of the final product”. This of course, means they will be complete shite. The pair he had in his hand at the launch, the photo behind him as he did said launch and the shoes shown on the website, are all different.
You’d have to be a complete mug to hand over $400, but the people who do so are about 8 years beyond help.
