Hammer and claw toes

What it is

Each toe is controlled by long flexor and extensor tendons coming from the leg, and by small intrinsic muscles within the foot itself. The intrinsics are what keep the toe flat; the long tendons bend it. When the intrinsics weaken, the long tendons pull unopposed and the toe buckles.

The consequence is more than cosmetic. A buckled toe rides up against the shoe and develops corns, and it drags the protective plantar fat pad forward off the metatarsal heads - which is why toe deformity and ball-of-foot pain arrive together.

What it feels like

• Toes bent up at the knuckle and down at the joints beyond it
• Corns on the tops of the toes and between them where they rub
• Callus and pain under the ball of the foot
• Difficulty finding shoes with enough depth
• Toes that were once flexible becoming fixed in the bent position

What causes it

Most people have more than one of these at once, and they feed each other. Read the list looking for the two or three that sound like your week rather than for the one true answer — the ones that describe you are the ones worth acting on.

Weak intrinsic foot muscles

The intrinsics hold the toes flat against the pull of the long tendons. Decades in shoes that immobilise the foot leaves them weak, and the tendons win.

Narrow and short toe boxes

Shoes that are too short or too narrow buckle the toes physically, and worn for years the joints remodel in that position. This is the single largest external factor.

High heels

Heels push the toes forward into the front of the shoe and hold them there, combining the length problem with a forward load transfer.

Bunions

A big toe drifting sideways crowds the second toe, which has nowhere to go but up. Hammer toe of the second toe alongside a bunion is a very common pairing.

A high-arched foot

Cavus feet have a characteristic clawing pattern because of the muscle balance around them. Toe clawing with a high arch is a recognised combination.

Nerve conditions

Peripheral neuropathy from diabetes, and inherited neuropathies such as Charcot-Marie-Tooth, weaken the intrinsics specifically and produce progressive clawing. Progressive deformity deserves a neurological look.

Inflammatory arthritis

Rheumatoid arthritis damages the small joints and the surrounding ligaments and produces severe, rapid toe deformity.

Age

Intrinsic muscle mass declines with age like everything else, so the balance shifts gradually over decades.

Progression from flexible to fixed

Early on the toe can be straightened passively. Left long enough the joint capsule contracts and the deformity becomes fixed - which is the point at which exercise stops being able to change it.

Who tends to get it

• Long-term wearers of narrow, short or heeled shoes
• Anyone with bunions, particularly affecting the second toe
• People with high-arched feet
• Anyone with diabetes or another cause of peripheral neuropathy
• Older adults, through intrinsic muscle loss

What makes it worse, and what settles it

The qFIT routine for this

Ready-made routineFoot & Heel Relief

qFIT already has this one built. It runs massage first, then stretching, then strength — the order that works on a body that is already sore — and every activity in it carries the reason it is there.

The button below opens your Checklist with this routine already selected, so instead of your whole list you land on just its Categories, Targets and Exercises, each with its checkbox, ready to tick as you work through them.

Have more than one problem? Tick yours under My Problems on My Profile and your Checklist's Routine list gains Recommended for my problems — every routine for the problems you picked, merged into one. Your picks stay private; that filter is the only thing they feed.

Get it checked if…

A rigid toe that cannot be straightened by hand will not respond to exercise; ulceration on the toe top needs urgent care in a diabetic

And whatever the body part: chest pain or unusual breathlessness on exertion; a fever alongside the pain; unexplained weight loss; pain that is constant and unrelated to how you move; new numbness, weakness or loss of bladder or bowel control; or one calf that is swollen, warm and painful. Any of those, stop and get assessed.

How it usually goes

While the toe is still flexible, footwear change plus intrinsic strengthening can improve position and reliably reduces the rubbing and the forefoot pain. Once the deformity is fixed, exercise cannot straighten it and the goals become comfort and skin protection, with surgery an option for persistent pain. Anyone with diabetes should have toe deformity taken seriously early, because the pressure points it creates are exactly where foot ulcers begin.

Others the same routine covers

These share the Foot & Heel Relief routine, so the work is the same. If one of them also sounds like you, that is a reason to expect more from it, not less.

This is general information, not a diagnosis, and it cannot examine you. If it matches you, use it to ask better questions of a clinician rather than to replace one.
