I can understand where you are coming from. I am just under 6'2'' (quite a bit above average) and I wish i could be taller like 6'5'' +. I guess it was because i was a very short child; which resulted in me wanting to be some kind of giant. But as there is nothing I can do about it, i dont try or worry really.
In regard to the shoes, i would not bother. Once you start wearing them, i think you will have a hard time taking them off, as the change will be so pronounced. I think this will cause more problems, as you will want to wear the shoes when ever you have company.
Your height is above average just be satisfied knowing that; you are not horribly short, you could benefit from being taller (as could most) but there is no real problem. As it stands, there is nothing much that can be done about height (apart from the shoes) and I think that could become something that would get ridiculed.
