This style of shoe is called a Paduka. It is made from wood and ivory and dates to the mid nineteenth century. Padukas are India’s oldest footwear. Their open design is suited to the climate, and they keep the sole raised above the sun-baked ground.
Within the Hindu religion, cows are considered holy animals and therefore footwear made of cow leather was not desirable. Footwear worn by holy people or in holy spaces was made out of wood, ivory, metal and sometimes camel leather. Holy men tended to wear very simple wooden padukas, whilst those worn by well-off worshippers tended to be more elaborate. Padukas can be easily removed before entering a sacred space like a temple.
The Hindu deities Krishna and Rama are often depicted wearing Padukas
