I
strongly recommend Foot Notes. This is the only resource that compiles the first two years of TUSPM's content into charts. While it is not a replacement for class notes, it is great when exams are coming around and you want to highlight the most important information. Also it comes in handy for part 1 boards. It's not a paperweight like USMLE First Aid.
LEA Survival Guide is optional. If you are a visual learner with anatomy, then it's useful. The course textbook is very cut and dry so its a useful supplement in that regard.
I would hold off on pocket podiatrics right now since you wont be in clinic for a bit. So spend your money elsewhere: scrubs, gloves, instruments, etc
