In the States. I have seen it mentioned on S and B before, but bit the bullet last week to order shoes in UK size 10.
They arrived in less than a week, all fit (in fairness, I have had the brand before, but can't get in my size in UK now)
With taxes and postage they worked out the same price I paid here 3 years ago, so I feel justified (£100 in taxes and postage 
)
