וָאַלְבִּישֵׁ֣ךְ רִקְמָ֔ה וָאֶנְעֲלֵ֖ךְ תָּ֑חַשׁ וָאֶחְבְּשֵׁ֣ךְ בַּשֵּׁ֔שׁ וַאֲכַסֵּ֖ךְ מֶֽשִׁי׃
수 놓은 옷을 입히고 물돼지 가죽신을 신기고 가는 베로 띠우고 명주로 덧입히고
Mishnah Yevamot
The commandment of halitzah must be performed in the presence of three judges, even though all the three are laymen. If the woman performed the halitzah with a shoe, her halitzah is valid, [but if] with a felt sock it is invalid. If with a sandal to which a heel is attached it is valid, but [if with one] that has no heel it is invalid. [If the sandal was tied] below the knee the halitzah is valid, but if above the knee it is invalid.
