Treatment: Will include a biomechanical, footwear and gait analysis assessment. Once the specific cause is located treatment can include offloading padding added to a simple insole.

A change in footwear may be warranted if the shoe box of your current footwear is either too narrow or not deep enough to provide adequate spacing of your toes.
Early detection and intervention can have you pain free about 75% of the time with conservative care mentioned above.
