Efficient!!!Love the shoes - fit is great. Delivery exactly as advertised! Royal Mail (love them - they're local!) What I wanted (fitflop due black leather 8) was in stock, fits beautifully, and were on my feet exactly when I expected. What's not to love? Will be ordering a second pair from the same place, so I don't run them into the ground. Now, patent? Or leather again..... Hmmm..... Fitflops are so good for my feet!
