Why do my toenails turn black from running? Important information regarding causes, treatment, and p

Running is a great NYC activity.  Whether on the streets, along the park paths, the loop in Central Park or over one of the bridges running offers countless rewards: breathtaking views, improved cardiovascular health, and the joy of achieving a personal record.

But running can also bring some unwelcome side effects, like black toenails. If you're a runner, perhaps you have encountered (or want to avoid) this common issue. 

Thankfully, prevention and treatment options are available.

At Manhattan Podiatry Associates, with two NYC locations:  Midtown and Downtown, we specialize in keeping your feet healthy and strong.That includes helping you understand the causes, treatments, and prevention strategies for black toenails.

Three Causes of Black Toenails in Runners:

• Repetitive Trauma
  Every stride you take can cause your toes to hit the front or sides of your shoes, leading to bruising under your toenails. This bruising occurs when blood vessels are damaged and blood pools under the nail, turning it dark purple, brown, or black.

• Ill-Fitting Shoes
  Shoes that are too tight push your toenails against the shoe, while shoes that are too loose allow your toes to slide forward with each step. Both scenarios create friction that can bruise your nails.

• Downhill Running
  Running downhill adds pressure to the front of your foot, increasing the risk of toenail injuries. If downhill training is part of your routine, balance it with other exercises to protect your toes.

Treatment Options for Black Toenails

Minor black toenails typically heal on their own with rest and icing to reduce swelling. However, severe cases may require professional care.

At Manhattan Podiatry Associates, we can:

• Drain trapped blood to relieve pressure.
• Treat acute trauma with procedures like trephination (draining) to prevent further complications.
• Address nail loss if the toenail falls off and guide you through the regrowth process.

Never attempt to drain a toenail yourself. Trust our Board Certified doctors to provide safe and effective care.

Prevention Tips for Black Toenails

Follow these strategies to keep your toes in top shape:

• Choose the Right Shoes: Select running shoes with ample toe room and proper support. A professional fitting at a running store can help you find the perfect pair.
• Trim Your Toenails Regularly: Avoid overly long or short toenails to prevent injury.
• Wear Quality Socks: Opt for moisture-wicking running socks with cushioning to reduce friction.
• Increase Miles Gradually: Avoid abrupt mileage increases to minimize stress on your feet.
• Perfect Your Form: When running downhill, maintain control and land softly to reduce toe impact.
