- Simply measure the length of the second metatarsal and compare that to the first. A longer second metatarsal is Morton’s toe. You can estimate the length by measuring the length of the toes from the heads of the first and second metatarsals.
- If the space between the first and second toe is deeper than the space between the second and third toe, that is Morton’s toe/foot.
- Do the knee bend test: From Posture Dynamics – “Without shoes, stand on a hard floor – your feet shoulder width apart, feet parallel and toes pointing straight forward. Do a ¼ knee bend. Keep your heels on the floor, and force your knees to move straight forward over your third toes. (imagine an invisible line from the center of your knee cap to your third toe.) If you have Morton’s foot you will feel your weight on the outside edges of your feet and little or no pressure under your big toes. From this position, move your knees slowly inward until you feel weight bearing pressure under the balls of your feet behind your big toes and on the inside edges of your feet. Stop moving your knees together when you feel equal weight over your first and fifth metatarsal. If the center lines of your knees moves past your third toes towards your big toes, you probably have Morton’s toe.” http://www.mortonsfoot.com/pickingrightpci.html
- A hypermobile big toe - hard to see unless the foot is in motion.
- An elevated big toe compared to the other toes. “An elevated first metatarsal can be observed when the feet are aligned so your knees travel straight over the middle of your feet when you do a knee bend. While the second through fifth metatarsals are firmly on the ground, the first, and strongest metatarsal is not on the ground and properly weight bearing. It is elevated.” Posture Dynamics.
- A callous under the second and third metatarsals instead of the first (normal when weight bearing is distributed over the first and fifth metatarsal correctly.)
- Severe Pronation as the foot attempts to ground the big toe leading to overworked lower leg muscles, OR
- In my case, supination also leading to overworked lower leg muscles.
- A duck footed (everted feet or splayed feet) gait.
- My tibial torsioned lower legs (knock knees) could have lead to increased strain on my knees leading to the two ACL injuries and multiple meniscal tears I've had from skiing.
- My life long duck footed stance and gait
- The huge callouses under my second and third metatarsal heads.
- The lower leg soreness and tightness, and sore feet at the metatarsal heads

|My homemade version of a Morton's foot fix|
|oh geez is this geriatric?|
I hope so.
What's really cool is just being able to think this through and experiment to find out what will work. I want to keep running for a long time. This is just another piece of that journey.
Oh and I signed up for Firetrails 50M October 11. So, as I begin to build mileage again for that little race for redemption I'll be interested to see how this "fix" helps my foot pain. I'm an experiment of one, so if needed I can go to a stiffer shoe, but for now, one variable at a time.
