Finally got to try on the shoes I received a couple weeks back, and it appears that sizing a half size up from my dress shoe size was dead on. Don't get me wrong, they're still snug, even with a slim no-show sock on, but I imagine a few wears will have them perfect. And they're just a beautiful, well-made sneaker.
With that said, I have a previous order in Snuff Suede / UK 9.5 (my standard dress shoe size) that I'd be willing to part with for the Drop price + shipping (or pickup in Philadelphia if that works for anyone). Again, that should roughly fit someone with a medium/narrow foot and typically a UK9 / US10 dress shoe (though I'm not offering any guarantees). They're unworn besides being tried on on carpet, and have had shoe trees in them since buying. Get at me if that interests anyone, otherwise I'll probably ebay them (or hookup a friend with a nice deal).
