The Rites of Hajj (Kitab Al-Manasik Wa'l-Hajj)
Dawud :: Book 10 : Hadith 1827
Narrated Aisha, Ummul Mu'minin:
Salim ibn Abdullah said: Abdullah ibn Umar used to do so, that is to say, he would cut the shoes of a woman who put on ihram; then Safiyyah, daughter of AbuUbayd, reported to him that Aisha (may Allah be pleased with her) narrated to her that the Apostle of Allah (peace_be_upon_him) gave licence to women in respect of the shoes (i.e. women are not required to cut the shoes). He, therefore, abandoned it.
