Corn and Callus Between the Fourth Toe: Why Identifying the Root Cause Matters
Learn why corns and calluses between the fourth toe keep recurring after laser treatment, and how a foot specialist at Gangnam Standard Orthopedics identifies the true bony cause.
A corn or callus between the fourth toe requires accurate diagnosis of the underlying cause at a specialist clinic.
We are Gangnam Standard Orthopedics, located near Gangnam Station.
Case: A patient in their 40s with a corn and callus between the third and fourth toes
The patient visited us with a corn and callus on the inner side of the right fourth toe. They had undergone approximately three laser treatments at a dermatology clinic elsewhere, but experienced no improvement due to persistent pain and repeated recurrence. After the latest recurrence, they sought out our clinic, Gangnam Standard Orthopedics, as a corn specialist near Gangnam Station.
At our clinic, the head physician — a board-certified foot and ankle specialist — personally conducts all consultations and performs all procedures. This allows us to address pain caused by corns and calluses between the toes and to progressively treat the associated walking difficulties.
The corn and callus between the fourth toe shown in the photos may look minor to some, but this type of inter-toe corn and callus can cause significant pain even after a short walk, and also leads to considerable foot fatigue in daily life.
Gangnam Standard Orthopedics — Corn and Callus Removal Specialist near Gangnam Station
Our head physician, Dr. Jo Ju-won, a board-certified foot and ankle specialist, has extensive experience treating pain caused by toe corns and calluses. His deep understanding of patients' discomfort allows him to truly empathize with what each patient is going through.
The corn and callus removal procedure is performed under local anesthesia. A thin-needle injection is used to numb only the top of the foot, which means the procedure itself can proceed without pain from the anesthesia.
When treating an inter-toe corn surgically, removing only the surface layer of skin is not sufficient and will not resolve the condition.

Because you have already experienced multiple failed laser treatments at other clinics, you will likely notice a clear difference between our approach and what you have encountered elsewhere.
At many clinics, the examination focuses only on the surface. The outer layer of the corn or callus is scraped away or treated with laser, and the treatment is considered complete.
However,
Treating an inter-toe corn or callus by addressing only the surface will inevitably lead to recurrence. It is essential to accurately identify the underlying cause before making a diagnosis and performing removal.
In the case of a corn and callus between the fourth toe, the toe bone was found to be excessively protruding inward (medially). This bony prominence is what causes the corn and callus to form in that area, leading to toe pain, discomfort while walking, and accumulated foot fatigue.

Can you see how the sharp bone spur has noticeably changed after the fourth inter-toe corn and callus removal procedure?
Without identifying the true cause — the underlying issue with the toe bone — other clinics repeatedly remove only the skin of the corn or callus with laser, only for it to recur again and again.
As a result, many patients with inter-toe corns end up visiting our specialized clinic after multiple failed treatments elsewhere.
Inter-toe corns can be properly treated when the diagnosis is accurate and care is provided by a board-certified foot and ankle specialist.
