What size should I order? 

You should measure your feet and refer to the size chart before ordering your pair to make sure you get the right size. Our Huaraches are generally a bit bigger than true to size. 

Is there a clear plastic protective film on the soles of the Huaraches?

Yes - there is a clear plastic protective film that needs to be removed before use. Under the film is a flat leather finish that will be less slippery.  It is kind of hard to notice but it is there! You can start peeling it from a corner - don't worry about scuffing up the sole as it will get scuffed with use anyways. 
Once removed your Huarache Sandals may not be returned or exchanged.
