TOENAIL PROBLEMS
Toenails were probably more useful to our distant ancestors who may have needed nails for tools and self-defense. Nowadays, toenails probably protect the toes, and may help with grip and balance. For athletes, toenails are literally on the frontline of physical activity, vulnerable to all sorts of damage. Especially in runners, toenail issues can be painful and annoying.
BLACK TOENAIL
WHAT IS IT?
Dark discoloration of the nail.
WHY DOES IT GET INJURED?
Bleeding under the nail (classic subungual hematoma) from toe hitting front of shoe while running.
SYMPTOMS
Discolored nail, pain and bleeding. Onset is usually gradual from repetitive trauma. It can develop rapidly during one race/workout (very painful!).
BEWARE
Dark discoloration in or under nails can also be from cancer (melanoma), bacterial infections, or problems related to blood circulation.

THICK TOENAIL
WHAT IS IT?
Abnormal thickening of the toenail.
WHY DOES IT GET INJURED?
Shoe trauma from sports, or fungal infection cause gradual thickening.
SYMPTOMS?
Involved nails will have a rough, chunky appearance, and get become brittle and cracked. Thick nails can become painful, especially in tight shoes or with workouts that are long or strenuous.
The nail will be difficult to cut properly.
BEWARE!
Fungal infections commonly cause thick toenails, so it’s worthwhile to see your doctor for s test to determine this possibility.

INGROWN NAIL
WHAT IS IT?
The corners of nails can grow sideways and burrow into the adjacent skin.
WHY DOES IT HAPPEN?
Improper nail cutting can trigger the nail to grow into the skin nearby. Tight, poorly fitting shoes can also cause or contribute to ingrown nails.
SYMPTOMS
At first, there may only be mild irritation associated with the nail contacting the delicate skin. As the nail dives into the skin, redness, swelling, and blistering can occur.
BEWARE!
If caught early, treatment is simple, but if the nail is fully ingrown, then you may have to consider nail surgery.
WHAT SHOULD YOU DO ABOUT TOENAIL PROBLEMS FROM RUNNING?
- Most toenail issues are cosmetic and may not cause much pain. However, they indicate something is wrong with your gear or training, so you should try to figure out a plan to fix the problem(s).
- Especially for pain, rapid worsening, lack of resolution, or other symptoms that concern you, SEE A SPECIALIST to confirm your diagnosis.
REGARDLESS OF THE TOENAIL CONDITION OR CAUSE, protecting the nail is always a good short term and long term strategy. Review this checklist of tips:
- Always cut your nails regularly and properly. Nails should be kept short, and cut square. Inspect the nails for early changes and intervene immediately as needed. Your podiatrist or doctor can review this with you.
- Choose shoes that fit well- big enough to give your toes space, but not so much that your foot slides forward.
- Always properly tie and untie your shoes, EVERY TIME, to ensure proper fit.
- Check your shoes: Your shoes may need to be replaced, or you may need shoes that better match your needs for support and cushioning.
- Do not run in shoes that are worn out because they cannot properly support your feet.
- You may have to decrease your mileage for a while until you are better.
- You may have to avoid hard running in speedwork, hills, and slippery/uneven trails until the nail improves.
- For the track and rough terrain, get shoes that match the activity. For example, trail shoes have features that give added protection for rocks and slippery surfaces. Track shoes must have the cushioning you need to protect your feet.
- Avoid wet and humid conditions, or get shoes and socks that will help keep your feet dry.
