What Is Intractable Plantar Keratosis (IPK)?
An IPK is a concentrated area of thickened skin on the sole of the foot. It often develops beneath a pressure point—such as the ball of the foot—and can make every step painful.
IPK vs. a Regular Callus
A typical callus
Usually a broader, flatter area of thickened skin caused by repeated pressure or friction. It may or may not be painful.
An IPK
Often has a small, dense central core that concentrates pressure deeper into the skin.
How it can feel
Patients sometimes describe the sensation as walking on a pebble, especially when bearing weight.
Understanding IPK
Overview
A focused, thickened skin lesion on a weight-bearing part of the sole.
Symptoms
Localized tenderness, discomfort when walking, or difficulty wearing certain shoes.
Contributing factors
Repetitive pressure, footwear, and the way weight is distributed across the foot.
Treatment
A podiatrist may reduce thickened skin and address the underlying pressure that contributes to recurrence.

IPK Treatment: Before, Procedure & Follow-Up
This photo series documents the treatment of a painful lesion beneath the fifth metatarsal area of the left foot. The patient initially reported severe pain at the site. The photographs show the initial presentation, stages of in-office treatment, and a later follow-up appearance.
How the Treatment Progressed
These photographs document the steps performed during the July 28 visit.
Individual findings and outcomes vary. Photographs document this patient's treatment course and do not guarantee a particular result. Images are displayed with appropriate patient authorization.
Eric was living with a super painful IPK.
Some IPK’S limit your activities and the types of shoes you can wear.

Real Patient Treatment Story
Eric’s IPK Treatment: From Painful Pressure to Follow-Up
An intractable plantar keratosis (IPK) is a concentrated area of thickened skin that can cause significant pain with walking or shoe pressure. These clinical photographs document stages of Eric’s treatment and subsequent images from his care.
Clinical photographs may show close-up views of treated skin. Images are presented as a treatment record; they do not establish that the condition is permanently resolved or predict another patient's results.

Additional Clinical Photographs
These three later-numbered photographs were supplied as part of Eric’s treatment story. Their exact dates and relationship to the IPK procedure should be confirmed before identifying them as follow-up results.
For more than 40 years, Dr. Ivar E. Roth has specialized in diagnosing and treating painful foot conditions, including Intractable Plantar Keratosis (IPK). His personalized treatment approach goes beyond simply trimming the lesion—it focuses on identifying the underlying cause, relieving pain, and helping reduce the risk of recurrence.

Why IPK’s Happen?
IPKs are almost always caused by excess pressure in one spot, often from:
Bone structure (Prominent Metatarsal Head)
Foot deformities (like Hammertoes)
Tight shoes or high heels
Abnormal gait / walking pattern
👉 In other words: your foot mechanics can create a pressure hotspot
Real Patient, Severe IPK’s Before & After
How it’s treated
Short-term relief
Professional debridement (trimming it down)
Padding / offloading the pressure
Keratolytic creams (like Urea)
Long-term fix (this is what actually matters)

What people get wrong
Most people treat an IPK like a cosmetic issue. It’s not.
It will keep coming back unless you fix the pressure causing it.
When to see a podiatrist
Pain when walking
Keeps returning after trimming
