My dear Oleg,

I am not sure that we have helped but it was interesting to hear the
story and it will be interesting to know the rest and the end!
About the boot I am using "the Ransart Boot" it is about the same that
you described. You can see it on my website: www.drisabelledumont.com.
If you need more details, just ask. Excuse me to answer so late...
Amitiés,

Isabelle
