Have your toenails felt a little sore or looked bruised after you get back from a run? Runner’s toe is when your toenail bumps against your shoe and leaves a blister under the nail, but it’s easy to prevent with a few simple changes to your routine. We’ll cover the best ways to keep your nails safe when you’re out on a run and how to care for them so they stay healthy.

1

Choose running shoes that fit properly.

  1. Shoes that are too small or large stress your nails. When you choose your running shoes, try them on before you buy them. Make sure there’s about a thumbnail’s distance between your toes and the fronts of the shoes.[1] Then, check that your running shoes hug the sides of your feet since you could get runner’s toenail if they’re too wide.[2]
    • Your feet can slip forward and jam your toenails into the fronts of your shoes if they’re too large.
    • Shoes that fit too tightly cram your feet at the fronts of your shoes so you feel the impact more with each stride, which could lead to bruising and blisters that turn your toenails black.

Wear socks that fit well.

  1. Socks that are too tight put pressure on your nails. A good pair of running socks also adds a layer of cushion between your nails and shoes so they don’t hurt after a run.[3] Choose socks that are made from a light cotton or synthetic blend since they’ll wick away sweat and moisture.
    • If you leave your socks on when they’re damp, it could lead to foot or nail fungus.
    • Try on your running shoes with your socks to make sure you still have space between the end of your toes and the front of your shoe.

Tie a lace lock into your shoes.

  1. Lace locks keep your heels from slipping forward while you’re running. When your feet slide forward, your nails take the force of the impact with each step and get bruised. You can tie lace locks with any pair of shoelaces.[4]
    • Lace your shoes with a criss-cross pattern up to the second-highest eyelet on each side of the shoe.
    • Take the left lace and feed it through the top eyelet on the left side of the shoe to form a loop.
    • Feed the right lace through the top eyelet on the right side of the shoe to make a second loop.
    • Pull the left lace through the right loop, and pull the right lace through the left loop.
    • Tie a bow knot to keep your laces secured.

Wear non-adhesive dressings for loose toenails.

  1. Non-adhesive dressings will keep your toenail safe without pulling it. If the pressure from running or a blister has made your nails feel loose, wrap a non-adhesive dressing around it before you put on socks. Change the dressing every day or when it gets dirty.[6]
    • It’s safe to put a non-adhesive bandage directly on your toenail, but avoid dressings with adhesive since they could painfully pull the nail out of the nail bed.

Trim your toenails every 3 or 4 weeks.

  1. Long nails are more likely to get damaged or ingrown. Cut your nails with a pair of clippers straight across following the natural shape of the nail. Keep your nails short so they don’t extend past the ends of your toes.[7]
    • Over-trimming your nails could lead to ingrown toenails.
    • You can trim the edge of a loose nail if it gets caught on your socks, but only if it doesn’t cause you pain.[8]

Take a break from running if you’re in pain.

See a doctor if you have severe pain or injuries.

  1. A doctor can safely treat any issues that you’re dealing with. If you’re feeling a lot of pain from a blister under your toenail or a loose toenail, contact your doctor and set up an appointment. They’ll be able to prescribe medication, drain a blister, or safely remove the nail to help speed up your recovery.[14]
    • Avoid trying to drain a blister or remove a nail at home since it can be painful and you’re more at risk of infection.
