Morphology
The meaning is directly derivable from 'lobate' (having lobes) + 'foot' — a foot with lobes or rounded divisions on the toes; a learner who knows both words can infer the anatomical, descriptive sense. This is a literal, descriptive compound rather than an idiom and follows common cross-linguistic compositional patterns, so it is immediately comprehensible.
Etymology
The noun lobate foot comes from the look of a bird's foot: each toe has a soft lobe along its side and the words lobate and foot describe that shape. These side flaps act like small paddles, so a lobate foot means a bird's foot with flaps that 'help it swim'.
