Bought these in Shimla. They have great rope soles but I am pretty sure the wool is man made fibre so these don’t really count more an example of what is possible
If you are still in India and near Jodhpur you can get some really cool leather slippers and sandals. These come in a huge range of styles from curley toed Ali Baba to simple mules. But the greatest recommendation of all is that they are all plastic free. These alone make it worth a visit.
