Key takeaways
- The second toe is the one most often affected.
- A flexible hammer toe has more options than a rigid one.
- Tight toe boxes are the most common contributing factor.
- Height inside the shoe matters as much as width.
Hammer toe is a deformity where one or more toes bend abnormally at the middle joint and curl downward instead of lying flat. The shape resembles a hammer, which is where the name comes from. Any toe can be affected, and the second is the usual one.
Severity varies. Early on it produces mild irritation from rubbing against shoes. As it progresses the toe stiffens and becomes harder to move, and the pain becomes persistent. Left long enough the joint turns rigid, at which point surgery becomes the main option.
The practical difficulty is footwear. A bent toe presses against the top of the shoe, producing blisters, calluses, and in some cases ulcers.
Four factors drive it
- Tight shoes. Narrow toe boxes squeeze the toes into unnatural positions and hold them there. High heels do the same by forcing the foot forward.
- Genetics. Inherited foot shapes and structural imbalances raise the risk regardless of what you wear.
- Muscle imbalance. When some foot muscles are weaker than others, the toe loses support and bends over time. This is common alongside flat feet.
- Previous injury. A sprain, fracture, or dislocation that altered the mechanics of the foot can produce hammer toe later, particularly where the injury healed poorly.
Shoe height matters as much as width
Most advice covers the wide toe box that lets the toes spread, and that is correct. The part people miss is vertical room. A bent toe sits higher than a flat one, so a shoe with a low toe box will press on it no matter how wide it is.
Beyond that, look for arch support that distributes weight evenly and takes stress off the toes, cushioning that absorbs impact, and breathable materials that keep the foot dry and reduce blister risk.
Birkenstock's deep, roomy toe box handles both dimensions well, and Altra does the same in running shoes. We fit both.
Exercises while the joint is still flexible
- Toe curls. Pick up marbles or a towel with your toes to strengthen the muscles.
- Toe stretching. Gently pull the toes apart to stretch the tendons and reduce the tightness pulling the joint into its bend.
These help most in the early stage. Once the joint is rigid, exercise maintains what movement remains rather than restoring what has gone.
Splints, pads, and orthotics
Toe splints encourage a more natural position and reduce pain. Silicone pads and gel sleeves cushion the toe and cut the friction that causes blisters. Custom orthotics help where the underlying cause is muscle imbalance or abnormal mechanics, and a podiatrist prescribes those alongside the right footwear.
When to get it looked at
- Pain that persists despite better shoes and self-care.
- Difficulty walking or taking part in ordinary activity.
- Signs of infection, including redness, swelling, or an open sore, which need attention immediately.
Surgery straightens the toe and corrects joint damage in severe cases. A podiatrist should assess whether you are at that point, and there is usually a good deal of ground to cover first.
