Actually yes, yes you are. You do not need someone sitting there as you wear a pair of boots, just say you want to get a better feel for them, and browse the shop for a while. Your excuses are just that, excuses, poor ones at that. When you get fitted, you should dedicate quite a few hours to it, as boots are the most important piece of gear you will buy and will make or break your skiing. Who cares if the shop isn't 10 min from your house, I drove 6 hours round trip to get fitted last, where I spent 6-7 hours trying on and feeling out many different boots. it sounds like you were just being another trendy kid that got FT's because that is what everyone else likes. Getting the wrong boots should never happen, that shows that you did not get properly fitted by someone who actually knows what they are doing and that you bought something based purely on word of mouth. Great job waisting a bunch of money and have fun with your shin pain, maybe you will learn something from this failed experience.
