Please make sure that you follow below steps:

2/ Extract the file you've just downloaded.

We recommend you only send us shoes you have tried on that fit comfortably so you do not potentially end up with a beautiful pair of custom stoned shoes that you cannot wear. Rather an expensive set of paperweights!
