Learning to walk on Ballet Heels

My boyfriend is really into high heels, the higher, the better. He really loves the highest shoes, I think more than each woman in the world! Unfortunately, I have to confess that I hardly had any experiences to walk on high heels before coming together with him. I even only possess few shoes, the fewest with higher heels.

However, for Christmas, I want to suprise him with buying some really high ballet boots for me. Before, I even did not know that such kind of shoes exists! I only know about those shoes, because my boyfriend is often watching videos on the Internet showing women walking on such really heigh ballet high heels.

And therefore, I thought that it could be a good idea to surprise him with them. However, I am afraid that I cannot walk on them because I have already problems with normal high heels. So, does anyone have some tips and tricks on me? I prefer a detailed step by step introduction so that I can learn it from the beginning.
