Funny Thing: Incredible Tall Boots On Train

Last week, while I was on the train, I spotted this guy wearing this pair of tall boots.
First, I did not notice and I thought he was just tall.
Then, he sat down and I saw the boots were incredibly tall.
The bottom part must be about 20cm!! About 6 inches!!
(see picture of black boot)

I took picture of boots only to make sure I did not violet privacy.
I was not sure why anyone would wear such pair of boots.

(Not sure why anyone would make it!!)
