IPA: /ˈʃuːləs/

Not wearing any shoes on the feet.

Shoeless → It is formed from "shoe" (from Old English *sceo*, meaning a covering for the foot) and "-less" (meaning without). The word "shoeless" means without shoes or lacking footwear.
Think of being 'without' ('-less') a 'covering for the foot' ('shoe') — that's why shoeless means not wearing shoes.
