You say you are a novice with no aspirations. What does that mean exactly? This is an important question. It goes along with how you answer the following questions:
Why do you ski?
What terrain do you want to ski on now? (Answered by your post.)
What terrain would you like to ski on?
Do you want to improve your skiing abilities?
How much you ski and what you want to do with your skiing will affect how much you are willing to spend on boots.
Right now, based upon your intial posting, buying boots and gear might not be a cost effective option for you. Not trying to talk you out of it, but, how many years of rentals will it take to get up to the price of boots, skis, and poles, when you only ski 1 or 2 times a year on the bunny slope?
There is also another option, buying used gear. I did this my first year skiing. Ask around at your local hil, if you have one. They can normally point you to a good seller. Also, there might be some used equipment that a ski shop may be willing to sell you.
If you care about skiing and want good fitting boots, get thee to a master bootfitter. You have a very narrow foot. (Like I do.) Getting a good fit will be a bit harder for you than the average Bear. However, boots are the most critical part of your ski gear.
