Pronunciation: [ʌnlˈe͡ɪs] (IPA) 
Unlace is a verb used to describe the action of removing laces from a shoe or other item. It is spelled using the letters u-n-l-a-c-e and the IPA phonetic transcription would be /ʌnˈleɪs/. The first syllable is pronounced with a short "u" sound, like the word "hut". The "l" and "a" in the second syllable create a "lay" sound, like "laying something down". The final "s" is pronounced with a soft "s" sound.
Unlace is a verb that refers to the act of loosening or undoing the laces or fastenings of a piece of footwear or other item that is usually secured with laces. The term most commonly applies to shoes or boots that are fastened with laces, but it can also be used to describe the action of unfastening any item secured in a similar manner. When one unlaces something, they typically untie or loosen the laces or cords so as to free the foot or remove the item.
The process of un lacing often involves gripping the laces firmly and pulling or tugging at them until the knots or bows become undone, gradually disentangling the tightly secured laces and allowing the person to remove the item or adjust it to their desired fit. Unlacing is usually required before one can slip their feet out of shoes or alter the tightness of the laces for comfort. The term unlace can also be used metaphorically to describe the process of undoing or unraveling a complex or entangled situation, much like untangling the laces of a shoe. In this context, unlace suggests a methodical or deliberate action aimed at resolving or simplifying a complicated matter.
To loose from a fastening of cord or string passed through holes.

The word unlace originates from the Old English term unlæsan. It is formed by combining the prefix un- (meaning not or reverse action) with the verb læsan (meaning to loosen or to untie). Over time, unlæsan evolved into unlace in Middle English, retaining the same meaning of to untie or loosen by removing laces.
