Dorsal web space between toes 1 and 2 is innervated by which nerve?

Explanation:
Understanding how the skin on the dorsum of the foot is innervated helps make sense of this. Most of the dorsal surface is supplied by the superficial peroneal nerve, but the tiny area between the first and second toes—the first dorsal web space—is supplied specifically by the deep fibular (deep peroneal) nerve. The saphenous nerve covers the medial side of the leg and foot, and the sural nerve supplies the lateral and posterior aspects. Therefore, it’s the deep fibular nerve that provides sensation to the web space between the big toe and the second toe.
