Factors that appear to contribute to Morton's neuroma include: 1  High heels. Wearing high-heeled shoes or shoes that are tight or ill fitting can place extra pressure on your toes and the ball of your foot.  Certain sports.
Morton's neuroma is a benign neuroma of an intermetatarsal plantar nerve, most commonly of the second and third intermetatarsal spaces, which results in the entrapment of the affected nerve. The main symptoms are pain and/or numbness, sometimes relieved by removing narrow or high-heeled footwear. Sometimes symptoms are relieved by wearing non-constricting footwear. Some sources claim that entrapment of the plantar nerve because of compression between the metatarsal heads, as originally proposed by Morton, is highly unlikely, because the plantar nerve is on the plantar side of the transverse metatarsal ligament and thus does not come in contact with the metatarsal heads.
