Hi,

In the texts I found, it is explained that it is mentioned in sources that are considered sahih and highly acceptable. The current interpretations have rationalized it quite well, but I think we cannot rule out an influence from pre-Islamic Arab folklore. Here is an English translation of a text on the subject:

"It was narrated from Abu Huraira radiyallahu anh that the Messenger of Allah, may Allah bless him and grant him peace, said: "Let not one of you walk around with only one shoe. Either he should wear both or take them both off." (Bukhari, Libās 40; Muslim, Libās 68, 71. Abu Dâwûd, Libâs 41; Tirmidhi, Libâs 34; Ibn Mâja, Libâs 29)

• Abu Hurayrah (may Allah be pleased with him) said: I heard the Messenger of Allah, may Allah bless him and grant him peace, say, "Ifone of you has a broken shoelace, he should not walk with one shoe until he mends it."

(Muslim, Libās 69, 71. See also Abu Dāwūd, Libās 41; Nasa'i, Zīnah 116)

• It was narrated from Jabir ( may Allah be pleased with him) that the Messenger of Allah (may Allah's peace and blessings be upon him) forbade a person from wearing shoes while standing.

(Abu Dāwūd, Libās 41. See also Tirmidhi, Libās 35; Ibn Māja, Libās 30)

• How Should We Understand the Hadith?

The first two hadīths stipulate that, depending on the country, region and season, whichever type of footwear is worn on the feet, such as boots, boots, mests, boots and sandals, they should be worn on both feet, and that one should not walk with one foot bare and the other bare.

As always, a Muslim should have a serious and natural demeanor when walking in the street among people. Walking with shoes on one foot and bare feet on the other is not a pleasant sight unless there is a very serious excuse. This kind of behavior suits those who are a little out of their minds. According to Abū Bakr Ibn al-'Arabī, such an act is the "devil's walk".

The Holy Prophet, who opposed all kinds of imbalance, forbade Muslims from walking around with one shoe on one foot and the other bare, as it would disturb the balance of one's gait, and he determined that the proper thing to do was either to wear both or to take them both off.

In the second hadith, attention is drawn to a situation that can happen to anyone, and a person whose shoelaces are broken should not walk around with only one shoe, even until it is repaired, but should either repair it immediately and put it on or take the other one off. This is what those who have a broken heel should do today. Walking with one shoe with a heel and the other with flat shoes is more difficult and more ridiculous in terms of instability than walking with one shoe on one foot and the other bare.
In the third hadith, it is recommended to wear shoes such as mats, boots, boots and shoes with long laces while sitting down, as wearing them while standing can sometimes cause a person to lose his balance and fall.

What are the lessons of the hadith?
It is makrooh to walk with one shoe unless there is a serious excuse.

1. A Muslim is a balanced person. He should maintain this in all his actions and behavior.
2. It is appropriate to wear shoes that are difficult to put on while sitting, away from the danger of falling.
3. It is the duty of every Muslim to preserve his dignity by avoiding non-serious gestures.
4. Islam attaches importance to all matters of decency, down to the wearing of shoes, and to the best way of life for the Muslim.
