Two main branches of superficial peroneal nerve: medial (intermediate) branch to medial side of hallux and second and third dorsal web spaces and lateral branch to third and fourth dorsal web spaces (A). Deep peroneal nerve courses between first and second metatarsals to innervate skin of first web space dorsally (B). Saphenous nerve courses anterior to medial malleolus and innervates skin over dorsomedial aspect of hindfoot and midfoot (C). Sural nerve passes posterior to lateral malleolus and divides near calcaneocuboid joint into dorsal branch (which innervates fourth web space dorsally) and main trunk (which continues distally to supply skin of lateral side of fifth toe) (D). In practice, however, branch of superficial peroneal nerve to dorsomedial aspect of hallux is most vulnerable to injury.
