Pain right under the ball of your foot, usually beneath the second toe, that has not settled despite months of arch stretches and new shoes? It may not be plantar fasciitis at all. One of the most common causes of forefoot pain is an injury to the plantar plate, a thick ligament-like structure that sits under the toe joint and holds the toe down.
It is worth knowing about, because the plantar plate is what stops the toe drifting upward or sideways, so a tear that is left alone can gradually change the shape of the foot. Here is what the plantar plate does, how an injury feels, how it differs from plantar fasciitis, what helps, and when it is worth getting your foot assessed.

What is the plantar plate?
The plantar plate is a thick, fibrous structure that sits directly underneath each of the small toe joints, on the sole side of the foot. Think of it as a firm strap that cushions the joint and, just as importantly, anchors the toe down so it stays flat on the ground when you push off.
Every step you take loads it. When you rise onto the ball of your foot to walk, run or climb stairs, the toe joints bend upward and the plantar plate is stretched and compressed at the same time. Over years of loading, or with a sudden overload, that tissue can be strained or torn. It happens most often under the second toe.
How does a plantar plate get injured?
Most people expect an injury to have a moment they can point to, but that is usually not how this one goes. Contributing factors commonly include:
Who it affects
Plantar plate injury is described as one of the most common causes of forefoot pain in clinical practice, and it is reported far more often in women, with a female to male ratio of around 10 to 1.
- Repeated loading of the ball of the foot over time, particularly with running, walking on hard surfaces, or standing all day
- A long second toe or a foot shape that puts more pressure through the second toe joint
- A bunion, which shifts load away from the big toe and onto the toes beside it
- High heels or shoes with a thin, flexible sole, which increase how far the toe joints bend under load
- A single overload, such as a sudden push-off, a stumble or a fall that forces the toe upward
Because it is usually a gradual process, many people put up with it for a long time before having it looked at.
What does a plantar plate injury feel like?
People often describe a combination of the following:
- Pain directly under the ball of the foot, most often beneath the second toe, rather than in the heel or arch
- A feeling of walking on a pebble, a bunched sock or a bruise that will not heal
- Swelling or thickening on the top of the foot near the base of the toe
- The toe starting to sit slightly raised off the ground, or beginning to drift sideways toward the big toe
- Pain that is worse barefoot, in flat flexible shoes, or when pushing off
That last point is the one worth acting on. A toe that is starting to lift or drift suggests the structure holding it down is not doing its job, and toe position changes are much easier to manage early than late.
How is it different from plantar fasciitis?
The two get confused constantly, but the location is usually the giveaway. Plantar fasciitis typically causes pain in the heel or along the arch, and it is classically at its worst for the first few steps in the morning, easing as you move.
Plantar plate pain sits further forward, under the ball of the foot at the base of the toe, and it tends to be worse the more you are on your feet through the day rather than first thing. It also comes with the toe-position changes described above, which plantar fasciitis does not cause.
If you have been treating heel pain for months and the sore spot is actually under your toe joint, that mismatch is worth having sorted out, because the two conditions need quite different management.
What helps a plantar plate injury?
The goal is to take load off the injured tissue while it settles, and then to address why it was overloaded in the first place. A typical plan can include:
- An assessment to confirm what is causing the pain and to check the position and stability of the toe
- Offloading the painful joint, often with padding or a metatarsal dome placed to redistribute pressure
- Taping the toe into a slightly downward position so the plantar plate is not stretched with every step
- Footwear guidance, generally toward a firmer, less flexible sole and a lower heel while it settles
- Orthotic therapy where foot mechanics are contributing to the overload
- A graded return to walking, running or sport, and strengthening for the foot and calf
Many people improve well with this kind of conservative management, particularly when it is started before the toe position has changed significantly. Where symptoms persist or the toe has already drifted, imaging or a surgical opinion may be discussed. If you would like your foot assessed, our team provides podiatry in Upper Mount Gravatt for people across Brisbane's southside.
When should you seek help?
Consider getting assessed if
You have pain under the ball of your foot that has lasted more than a few weeks, it feels like walking on a pebble, there is swelling near the base of a toe, or you have noticed a toe starting to lift or drift sideways. Seek prompt care if the foot is very swollen, you cannot bear weight, or the pain came on suddenly and severely, so other injuries can be ruled out and your plan tailored to you.
Helping You Perform at Your Best
Ball-of-foot pain has a habit of being tolerated for months, and it is much easier to manage before a toe changes position. At ACE Sports Medicine in Upper Mount Gravatt, our podiatrists assess forefoot pain properly, work out what is overloading the joint, and build a plan around offloading, footwear and a staged return to what you enjoy, for people right across Brisbane's southside.
