This is a very good self levitation however not for everyone. I found it to be impractical in many
ways only one of which is the distruction of a set of otherwise good shoes. You can not use it in
all situations and walking around with it on all the time is not appealing either. If you want to
make some great video or for a promo shot this may be a good effect. It was interesting to read and
learn the method but not for me.
