Some anti-Ahmadi opponents raise the allegation from Seeratul Mahdi, volume 1, page 60 narration 83, which mentions that Hazrat Ahmad (as) sometimes wore his shoes on the wrong feet. Firstly, the word used is Gargaabi, and these were unique type of shoes and you would not be able to tell at first glance which one is the right shoe and which one is the left one.

This detachment occurs because they do not find the time to focus on the world and are always engaged in Zikr and responsibilities which Allah has assigned to them. This is why the Prophet Muhammad (sa) said that you people know more about the worldly matters.
The Prophets have always lived like this, where they do not care about such little details of clothing. The saints also lived like this. Allah States:
قُلْ إِنَّ صَلَاتِي وَنُسُكِي وَمَحْيَايَ وَمَمَاتِي لِلَّهِ رَبِّ الْعَالَمِينَ
Say, ‘My Prayer and my sacrifice and my life and my death are all for Allah, the Lord of the worlds. (Chapter 6, Verse 163)
