WHAT IT’S REALLY ABOUT
Strengthen Your Feet: Preventing Injuries, Falls, and Choosing Better Footwear
- Conley explains the foot's three regions, its 26 bones and 33 joints, and the massive loads it handles, arguing most injuries arise in the forefoot because of weakness or instability rather than simply overload.
- Common problems such as plantar fasciitis, bunions, hammer toes, hallux limitus, and Achilles tendinopathy are framed as results of weak intrinsic and extrinsic muscles and cramped footwear, best addressed with progressive loading rather than rest, bracing, or reflexive surgery.
- Toe strength, ankle mobility, and sensory decline are discussed as major predictors of falls with age, and she describes simple tests, including a toe dynamometer, an anterior fall envelope wall lean, and a vibration tool.
- Limited ankle dorsiflexion and poor proximal stability can cascade up the chain into knee and low back problems, and Conley argues that control matters more than perfect posture.
- Her footwear advice centers on a wide toe box, low or zero heel-to-toe drop, and moderate cushioning, with gradual transitions, toe spacers, and foot work outside the shoe for anyone wearing performance or fashion shoes.
IDEAS WORTH REMEMBERING
5 ideasMost foot injuries happen in the forefoot, and many stem from instability or weakness.
Conley says about eight times body weight passes through the forefoot at push-off, and stress fractures on the medial side like the navicular come from tensile strain when motion can't be controlled.
Plantar fasciitis is often a signal of a weak foot.
She links it to weakness of flexor digitorum brevis, advises that orthotics are only a short-term load modifier with an exit strategy, and says chronic cases need loading and strengthening rather than offloading.
Toe strength is the biggest predictor of falls in older adults.
Conley cites a target of about 10% of body weight through the big toe and 7 to 8% through toes two to five, along with a wall-lean test of 4.5 inches or more, and notes foot sensation and strength decline with age.
Tendons and bones need load to heal, and isometrics can calm pain.
Rest may feel good but leaves the tissue unprepared on return, while she calls isometrics her pain meds because they reduce cortical inhibition after injury.
Limited ankle dorsiflexion causes compensations up the chain.
She describes early heel rise, knee hyperextension, and forward bending at the hips as ways people cheat, and advises aiming for about 35 degrees rather than the 10 needed to walk.
