As a prospective podiatry student, I bought this book after having had a good look at the 7th edition. They are largely the same but a few chapters are different. The main attraction was the online resources. I duly bought the book, only to discover that the online resources weren't ready. As I write (1st September 2010) the online resources are still incomplete: the videos and multiple choice questions aren't available but the pictures and powerpoints are available. It's a it of a faff registering and the U.S team doesn't reply to my emails which point out they should let their customers know they are buying an incomplete product.
Let's hope that the online resources will be available soon. Otherwise this seems like a pretty authoritative text for a podiatry student although I'd recommend reading Anatomy and Physiology for Dummies first so as you understand the terms if you're new to the area!
