"Super everter, deep dorsiflexer."
Superficial peroneal nerve (superficial fibular nerve) supplies the fibularis longus (peroneus longus) and fibularis brevis (peroneus brevis). These muscles
evert the foot.
The
deep fibular nerve (deep peroneal nerve) supplies the tibialis anterior, extensor digitorum longus, fibularis (peroneus) tertius, and extensor hallucis longus (propius). These muscles
dorsiflex the foot.
Foot drop is due to deep peroneal nerve palsy. You can remember Drop and Deep as they both start with D.
The skin over the
greater part of the dorsum of the foot is supplied by the
superficial fibular nerve with the exception of the first web space, which is innervated by the deep peroneal nerve.
You can remember most of the superficial stuff (the skin) is supplied by the superficial nerve!
