A mallet toe is a toe deformity where the joint closest to the tip of the toe bends downward and stays curled. It most commonly affects the second, third, or fourth toes and develops gradually as the tendon controlling that joint tightens and contracts over time. The condition starts out flexible, meaning you can still straighten the toe manually, but eventually becomes rigid and fixed in the bent position.
Which Joint Is Affected
Each of your smaller toes has three joints. Mallet toe specifically involves the joint nearest the toenail, called the DIP joint. This is what distinguishes it from two similar-looking conditions. A hammer toe bends at the middle joint, while a claw toe involves the joint at the base of the toe buckling upward (often with the other joints curling down as well). The distinction matters because the joint involved determines which treatments work best and how the deformity progresses.
From the outside, a mallet toe looks like the very tip of the toe is pointing downward. The toenail may press into the ground or rub against the inside of your shoe, which is often how people first notice something is wrong.
Common Causes and Risk Factors
Mallet toe develops when repeated forces cause the tendon on the underside of the toe to shorten and tighten. The most common culprits are shoes that crowd the toes, particularly narrow shoes and high heels that push the toes forward into a compressed position. Over months or years, the tendon adapts to the shortened position and eventually locks in place.
Other contributing factors include:
- Previous toe injury, such as a stubbed or broken toe that healed in a slightly bent position
- Foot structure differences present from birth, like a second toe that’s longer than the big toe
- Arthritis in the foot or ankle, which changes how forces distribute across the toes
- Neuromuscular disorders that affect muscle balance in the foot
People with conditions that reduce sensation in their feet are at higher risk. Diabetes, peripheral neuropathy, and peripheral artery disease can all dull feeling in the toes, making it easier to walk with a toe in an awkward position or sustain small injuries without noticing. Over time, this leads to the kind of repetitive stress that causes the tendon to contract.
Symptoms and What to Watch For
The most obvious sign is the visible downward curl of the toe tip. In the early stages, you can still manually straighten the toe, and it may not hurt at all. As the deformity progresses, pain and other symptoms typically develop.
Because the curled toe changes how your foot sits inside a shoe, friction builds up at the tip of the toe and on top of the bent joint. This friction produces corns, which are small, round bumps of hardened skin that form on the tops and sides of toes. You may also develop calluses on the ball of the foot as your weight shifts to compensate for the bent toe. These areas can become red, irritated, and painful, especially in closed shoes.
Left untreated, a mallet toe that started as a minor annoyance can progress in a few ways. The toe can become permanently rigid, making it impossible to straighten without surgery. Corns and calluses can crack, creating openings for infection. For people with diabetes or poor circulation, even a small wound on a toe can become a serious medical issue, so catching mallet toe early is particularly important in those cases.
Non-Surgical Treatment
When mallet toe is still flexible, non-surgical approaches focus on relieving pressure on the toe and preventing the deformity from worsening. The single most impactful change is footwear. Shoes with a wide, deep toe box give the toes room to lie flat instead of being compressed. Avoiding high heels and pointed shoes removes the forward pressure that drives the tendon to contract further.
Cushioned pads or toe sleeves placed over the bent joint can reduce friction and prevent corns from forming. Some people benefit from toe splints or taping, which gently hold the toe in a straighter position and can slow the progression from flexible to rigid. Over-the-counter arch supports or custom orthotics help redistribute pressure across the foot, taking stress off the affected toe.
Toe exercises can also help maintain flexibility and strengthen the small muscles in the foot. Simple stretches done barefoot, like lifting all your toes off the floor and holding for five seconds, or pressing individual toes down against resistance, improve control and range of motion. Repeating these 10 times per session, once or twice daily, keeps the joint from stiffening as quickly. These exercises work best when the toe is still flexible and are less effective once the deformity becomes rigid.
When Surgery Is Needed
If the toe has become rigid and non-surgical measures aren’t controlling the pain, surgery is the next step. The most common procedure for mallet toe is a flexor tenotomy, where the tight tendon on the underside of the toe is cut through a small incision near the base of the toe. This releases the downward pull and allows the toe to straighten. It’s a relatively minor procedure, often done under local anesthesia.
For more severe or long-standing deformities, a joint fusion may be recommended. In this procedure, the bent joint is straightened, a small amount of bone is removed, and the joint is held in position with a temporary pin or small implant while it heals. The joint fuses into a straight, stable position permanently.
Recovery After Surgery
Recovery timelines vary depending on the procedure, but most people follow a similar pattern. You’ll wear a special protective shoe for three to six weeks to keep the toe aligned while it heals. Stitches come out around the two-week mark. If a temporary pin was placed to hold the toe straight, it’s typically removed three to six weeks after surgery.
Standing and walking for extended periods won’t be comfortable for at least three to six weeks, sometimes longer. Most people can return to regular shoes once the protective period ends, though swelling in the toe can linger for several months. The corrected toe won’t bend at that joint anymore if a fusion was performed, but most people find this a worthwhile trade-off for eliminating the pain and deformity.
