wiktionary
From Middle English sho, shoo, from Old English sċōh(“shoe”), from Proto-West Germanic *skōh, from Proto-Germanic *skōhaz(“shoe”), of unclear etymology; possibly a derivation from *skehaną(“to move quickly”), from Proto-Indo-European *skek-(“to move quickly, jump”).
Eclipsed non-native Middle English sabatine, sabatoun(“shoe”) from Medieval Latin sabatēnum, sabatum(“shoe, slipper”) (compare Old Occitan sabatō, Spanish zapato(“shoe”)).
The archaic plural shoon is from Middle English shon, from Old English scōn, scōum(“shoes”, dative plural) and scōna(“shoes'”, genitive plural); it is cognate with Scots shuin(“shoes”).
