The spaces in the sole of the foot are : four median plantar spaces MI MII MIII and MIV lying between the plantar aponeurosis and the four layers of the muscles in the intermediate part of the sole— a series of lumbrical spaces and medial plantar space lateral plantar space deep medial plantar space and deep lateral plantar space in association with the muscles in the lateral and medial p [...] The subcutaneous space is continuous around the toes except at the inner border of the proximal phalanx of the great toe and the outer border of the proximal phalanx of the little toe where the sucutaneous tissue is adherent to the periosteum. [...] behind the previous one and it passes through the base of the first metatarsal and the proximal parts of the shafts of the second third and fourth and through the middle of the shaft of the fifth metatarsal. [...] On the fibular aspect the dorsal subcutaneous space is limited where the subcutaneous tissue is adherent to the outer surface of the cuboid and on the medial aspect it comes down very near the outer margin of the abductor hallucis where the subcutaneous tissue is adherent to the medial border of the plantar aponeurosis. [...] Thus it can be appreciated that infection reaching any of the muscle tendons in the foot can easily spread up along the length of the tendon and the muscle in the interval between the fascia investing the muscle and the investing layer of deep fascia or the first or second fascial septum as the case may be.
