Arthashastra
उलूक गृध्र वसाभ्याम् उष्ट्र चर्म उपानहाव् अभ्यज्य वटपत्त्रैः प्रतिच्छाद्य पञ्चाशद् योजनान्य् अश्रान्तो गच्छति ॥
When a man makes a journey, wearing the shoes made of the skin of a camel, smeared over with the serum of the flesh of an owl and a vulture and covered over with the leaves of the banyan tree, he can walk fifty yojanas without any fatigue.
