The Mishpacha profile (referenced in my last post) quoted 2 reasons for this minhag, one a typical Chasidish story and one a very practical reason:
- One of the previous Rebbes went to visit his brother for Shabbos. On Erev Shabbos he put on the traditional white knee high socks, however, he saw that his brother was not wearing white socks because he was too poor to afford them. In order not to embarrass his brother he put on his high boots for Shabbos.
- Skver located in the Ukraine is a very cold place and therefore they wore boots all the time to keep their feet warm.
The question that we can ask is what is the relevance of wearing boots today? Especially according to the second reason, why wear heavy boots in a warmer climate where everyone has heat? Why did clothing styles get frozen in the style of 150-200 years ago?
