Black Toe Nails from running?

Your shoes may not fit well.

Shouldn't happen with the right shoes (unless you are doing a lot of downhill or intense trail running). Go up a size from street shoes in your running shoes. Feet can swell over the course of a run.

I get these from basketball alllll the time.

Like you said, just let them grow out and fall off...
I'm praying mine are gone before summer haha

Black Toe Nails from running?

I would have to agree with the posters who'd suggested, that you may have improperly fitted footwear. I have been walking/running long distances since the end of September and I have yet to encounter this issue. Try to make certain you have enough wiggle room in the toe area of your runners and socks(mentioned by another poster too@Armour brand). If they are too tightly wedged in, you hurt and injure the toenail. Try to purchase some runners 1 size up from your normal shoe size. Due to the fact that you might be a fairly new runner(walker for walkers), your feet will swell and if it does happen, then you NEED to accommodate it. If you do not, you will be forced to deal with black toe nails.

I'm going to agree with many posters before me - it is probably the shoes. I worked in a specialty running store and fitted shoes all the time, and we fitted shoes to people anywhere between .5 and 1.5 sizes larger than their street / dress shoe size. Occasionally I would have customers who would try on the shoes I brought out without looking at the boxes, pick the ones that she liked best and was most comfortable, and then was really surprised at the size My dress shoe size is 7.5/8, and my running shoe size is 8.5. The idea is you want to have comfortable wiggle room in your toes. Pressing your thumb down on the tip of your shoe, you should have at least .5-.75 inches before the end of your toe.

I started running again recently and this happened to me too! Don't mind the excuse for new shoes though

Get properly fitted, don't just go for a size up. You might find it's not just about shoe length but also shoe width so ensuring you're properly fitted is incredibly important.

Also make sure you're wearing good socks, I personally LOVE thorlo socks. And keep your toenails trimmed really short!

You can't really do anything now, paint your toenails so it's not as obvious, tape the nail down with strapping tape when it starts to come off and flaps around a bit and pull it off when it's ready. Oh and you might find onece the nail's gone you blister easily on the top of the toe where the nail should be, so keep something handy (bandaid. blister pad etc) to stick over it when you're training.

Make sure that you have good shoes (like everyone else has said) and make sure that you have good socks too. I lost 2 1/2 (yes that's right) for an 11 mile run two weeks ago. Wear your black toenails as a badge of honor!
