This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
The exact historical development of 踅 is uncertain. It visually combines 折 (top) and 足 (bottom), but the original semantic or phonetic role of these components is unclear.
The top component 折 suggests breaking or folding, and the bottom 足 means foot. Imagine a foot that is broken or folded, causing a limp or hobbling motion.
For テイ, picture a person with a broken foot trying to walk, but they can only manage a tiny, teetering step: tiny -> テイ.
