I ordered the same size as my adidas Pure Boost size and they fit the same.
For reference I'm a 7.5 in these and the Pure Boosts and an 8 in most Nikes like the Flyknit trainers
Yeah I ordered a pair the other day, but was having some cart issues too
As soon as you add it to the cart you have to complete the order, you can't go back in the app
also make sure you use the promo code: CUSTOM to get 20% off
I've ordered from there twice and it has taken about 7-10 days to get to CA
I haven't been charged any custom fees but this first order sat it customs for like 4 days before it went out to USPS
