Those pictures reveal the practice that is called "foot binding" it occurs in Tibet and other parts of Asia (specifically SE Asia). In the culture of the tribes who practice foot binding, it is believed that if a woman has small feet it is beautiful and ideal, and for some marital reasons. Therefore, many women suffer at the pain-staking practice of foot binding.
Excerpt below:
"Author Yang Yang says that women with tiny feet were a status symbol who would bring honor upon the entire clan by their appearance.
"Some married women with bound feet would even get up in the middle of the night to start their toilette, just to ensure they would look good in daytime," he says.
In Liuyicun, the practice persisted so long because of the village's economic prosperity — and its inhabitants' desire for obvious wealth signifiers, like daughters with bound feet."
"At that time, bound feet were a status symbol, the only way for a woman to marry into money. In Wang's case, her in-laws had demanded the matchmaker find their son a wife with tiny feet. It was only after the wedding, when she finally met her husband for the first time, that she discovered he was an opium addict. With a life encompassing bound feet and an opium-addict husband, she's a remnant from another age. That's how author Yang Yang, who's
written a book about them, sees these women."

I hope this answers your question to why foot binding is done in some societies.
