Runners

Your shoes are too tight in the toe box! I don't have any home remedies, but to buy new shoes, sorry!

Shoes. Unless you are an ultra runner doing some serious downhill.

I am short both the toenails from my big toes right now. I am training for a marathon, and I have been doing much more downhill running than usual. I am glad to have lost them before the race, so that I won't have to worry about losing them on race day.

In my case, it's a symptom of the nail of my big toe hitting the inside of the shoe. I'd rather lose the nails periodically than run in a larger shoe. I've looked up toenail removal, and I don't quite have the guts to ask a doctor to pry a healthy nail off and dump chemicals on the nail matrix, but I won't be upset if they don't grow back.

Once you've lost a nail, I think the only remedy is to wait for it to grow back. If there's a blister behind the nail, and the toe feels swollen, I am not above draining it - but I Am Not A Doctor, and I didn't even stay at a Holiday Inn Express last night (it's probably not recommended...) I'm not sure if the nail would recover if you leave it alone, because I haven't got that kind of patience. But I've made my peace with losing the nail, anyway.

It always happened to me too. I never found a solution other to stop running. My toenails are still damaged and it's been 5 years or more since I stopped. It's from your foot jamming forward against the toe box of your shoes. It's bruising is turning them black.
