If a person in the state of ihram wears a sandal that is closed at the front and open at the back, is there anything required of him?

The questioner : My Shaykh, if a person in the state of ihram wears a sandal that is closed at the front and open at the back, is there anything required of him?

The Shaykh : If it is below the ankles, there is nothing required of him.

The questioner : But does it matter if it is closed at the front?

The Shaykh : How do you mean closed at the front?

The questioner : If it is closed at the front, like a shoe for example, and open at the back.

The Shaykh : From the front to where?

The questioner : Like this shoe, Shaykh.

The Shaykh : I do not see it, my brother, may Allah guide you.

The questioner : Like this.

The Shaykh : No problem.

The questioner : Is there nothing required of him?

The Shaykh : There is nothing required of him.
