Corn vs. Callus – A Quick Overview
You hear people talking about corns and calluses all of the time (or at least I do anyways), so… what is the difference?
What is a corn vs. callus?
Let me begin by saying that corns and calluses are very similar as they are both areas of thick, dead skin caused by friction and/or pressure.
In addition, both a corn or a callus may or may not be painful.
The determinants between a corn vs. callus come down to simply the appearance and the location, or part of the body, where this friction or pressure has caused your (overly-annoying and often painful) thick skin to occur.
Both corns and calluses are more common in people who have sweaty feet, stand for long periods at a time and wear ill-fitting shoe gear.
Corn vs. Callus – Let’s Talk About Location
As stated above, you can quite simply determine if you are suffering from a corn vs. callus primarily by the area of the body that is affected.
A corn typically occurs solely on the toes.
When a corn occurs within the webspaces (area of skin between the toes), we typically call the corn a soft corn. Corns located on the tops of your toes are usually referred to as a hard corn.
A callus, on the other hand, routinely surfaces on the hands or feet (excluding the toes).
The most common locations for calluses to occur on the feet include the bottom of the heels and below the bony areas of the balls of the feet.
So… are there any other differences between a corn vs. callus other than simply location?
Corn vs. Callus – The Differences in Appearance
While corns and calluses, at first glance, usually seem to be very similar in appearance, if you look a little closer, you will see some very obvious differences in a corn vs. callus.
Both types of corns are typically smaller in size than calluses.
They are generally circular in shape and have a clearly defined center. Depending on the type of corn, this center can be hard or soft.
Soft corns (remember… these are corns located on the skin between the toes) usually have the most distinct characteristics between the three.
Soft corns, while still comprised of thick skin, typically have a more moist, whitish appearance to them.
Upon touch… they distinguish a soft, rubbery feel (hence the name “soft corn”).
Most of the time, these soft corns can mimic an open sore as the skin is built up around its edges and tends to “crater” in the middle of the lesion.
Hard corns, (located on the top of the toes) on the other hand, appear as a firm, thick build-up of dry, or dead, skin.
These corns are usually small in size, round in shape and well-defined.
Usually, if you really inspect closely, you will see a ring within the hard corn.
The outside edges of this ring are typically soft and yellow, while the inside portion of the ring is very hard and gray.
It is typical to find inflamed, or red skin, surrounding the corn.
Calluses (located on the hands and anywhere else on the feet) give the impression of simply hard, dry and thick skin.
A callus can portray a mildly grayish, palish or yellowish color; but, this is not always the case.
Upon running your hand over a callus, you may feel a lumpy texture about the skin.
Corn vs. Callus – Which One Hurts Worse?
As stated above, both a corn and a callus may or may not be painful when pressure is applied to the lesion.
We do typically see, however, that pain is more common and usually more intense with a corn vs. callus.
This pain, when present, also typically exhibits a different behavior in a corn vs. callus.
When a corn is palpated (or pressure is applied), if pain is present, the highest amount of pain is directly over the lesion… on top of the thick skin.

Corn vs. Callus – Why Do They Form?
To begin, corns and calluses are not caused by a virus or bacteria and are NOT contagious.
So… how and why do we get them?
While the location and appearance of a corn vs. callus definitely reveal differences amongst the two, the causes of both corns and calluses are identical (with a small addition to the soft corn).
All corns and calluses, as briefly stated above, are caused by the culprit of repeated friction or pressure on a particular area of skin.
This pressure (and/or friction) results in direct damage to the skin that it is imposed on.
Our bodies react to this imposition and respond to the damage.
Essentially, in its attempt to address and repair the damage, it protectively creates a hard surface over the area which we term a corn or callus.
What Causes A Corn vs. Callus?
Anything that can cause friction or pressure to your skin can cause both a corn or callus.
Typically, calluses on the hands are caused from pressure by any repetitive handling of a tool or object.
Some examples of these can include a gardening hoe, hammer, tennis racket and lifting weights.
Some causes of corns and calluses on the feet can include the following:
- Shoes that are too tight and cause pressure
- Shoes that are too high-heeled and cause pressure on the sole of the foot
- Shoes that are too loose and cause friction
- An exaggerated seam within a shoe that causes friction
- Socks that do not fit well or the absence of socks
- Walking barefoot regularly as the skin will naturally thicken to protect itself
- Foot deformities – bunions, hammertoes, claw toes, mallet toes, bumps caused by Rheumatoid Arthritis
- Repeated actions – pressure due to sports, jogging or walking
- Abnormal gait (odd way of walking)
- Bone structure – flat feet or bone spurs
- Advanced age – less padding on the balls of the feet
Corns vs. Callus – How Shoes Can Make An Impact?
While some causes of corns and calluses are unpreventable, there are some things that we CAN do to minimize our risks of developing these annoying conditions… especially when it comes to shoes!
I have summarized several ways to eliminate the risk of corns and calluses directly due to shoe gear below!
Only buy properly fitting shoes.
When making a shoe purchase at your preferred shoe store, it is essential to have BOTH feet professionally measured in BOTH length and width in order to ensure the proper size selection.
ALWAYS try BOTH shoes on and walk around the store!
You should ensure that the end of the shoe is no closer than a half of an inch to your longest toe.
Can you wiggle your toes? If not… the shoe is simply too tight.
Shop for new shoes at the end of the day.
Why you ask?
Our feet naturally swell throughout the day.
To avoid the issue of your shoes becoming too tight in the evenings, you want to ensure that you purchase shoes that will accommodate for this.
Be smart with your shoe style.
Avoid shoes with extremely high heels and sharply pointed toes.
Wear as low of a heel as possible!
If you MUST wear this style of shoe for work… minimize the damage by investing in a nice pair of athletic shoes to wear to and from work (and on your lunch break) to give your feet a break from all of the added pressure points that heels cause.
Also, if you have structural foot deformities, make sure that you will select a style of shoe that will accommodate for this.
For example, if you have hammertoes (a condition in which the toes buckle up), make sure that the shoe that you select either has a toe box with extra depth to it OR a toe box that is constructed of flexible material that will move with your deformity.
Watch the “wear” pattern on the soles of your shoes.
As you put the miles on your shoes, eventually the internal lining and soles can wear down.
When this occurs, the ability for our shoes to act as a shock absorber for the hard surfaces that we walk on is substantially decreased.
To avoid this, have the soles of your shoes replaced regularly or simply realize that it is time to invest in a new pair.
Also, you want to check for even “wear” on the soles and heels of your shoe.
Uneven “wear” patterns could signal that you have an abnormal gait cycle that is causing an increased pressure point to a particular area of your foot.
Corn vs. Callus – Other Simple Preventative Measures
Wouldn’t it be great if we could prevent corns and calluses from showing up in the first place?
You already know how to ensure that inadequate shoe gear doesn’t contribute to the formation of these annoying ailments, but what else can you do to be pro-active?
The following are simple recommendations to decrease the likelihood that you will develop both corns and calluses:
- Wash your feet every day. Use water, soap and a scrubbing brush. Following… ensure to dry your feet thoroughly.
- Do NOT use body lotion on your feet. Instead,… invest in a moisturizing foot cream made especially for the feet.
- Remove hard skin gently and regularly. This is best performed with a foot file or pumice stone.
- Wear padded gloves or utilize tools with padding in order to protect your hands when handling tools.
- Wear comfortable socks in order to reduce friction to your feet caused by some shoe gear.
- If foot deformities are present, invest in pads and cushions to reduce pressure points and friction. I have listed some of my favorites below.
Corn vs. Callus – Final Words
As you can see, there are both many similarities and differences between a corn vs. callus.
Neither of these two foot ailments are fun to deal with and pain can occur.
Whether a corn vs. callus, there ARE things that you can do to lessen the likelihood of you having to suffer from the annoying problems that having either of these can cause.
Be proactive and take the steps necessary to ensure that your risk of developing a corn and/or callus is minimized.
