I had purchased these boots to be used for my Jedi Knight costume.  I am very satisfied with this product.  Not only did it arrive to my house extremely fast, but the boots are very comfortable.  I wear a size 13 shoe and I ordered the 'Large (12-13)' boot.  There is a zipper on the inside calf of each boot to easily fit your leg into the boot, however I am able to put these on without using the zipper.  I noticed that some other people stated that their calf did not fit inside of the boot.  I am 6'2" and weight 160lbs and this was not a problem for me.  In order for your calf to not fit inside of the boot, you have to have a VERY large calf.  Overall, these were very comfortable boots and I see absolutely no problems with them whatsoever.  I am going to have an excellent Halloween!
