That may be an option at some retailers, but, on the whole, UK
retailers will not accept payment in US dollars. Due to the ever
changing nature of currency exchange rates, UK retailers will generally
only list products in GBP. As an overseas customer, your credit
card will be charged the amount in pounds sterling, and then your
credit card issuer will convert the charge into your local currency.
Most banks and credit card issuers will implement an additional
charge for any currency exchange. You may want to use an online
currency converter before making an order from a UK footwear retailer,
to double check what you will be charged in dollars.
