Does anyone have any advice of what I can do to power through running an upcoming 5k run this Saturday mornin' with a fairly small foot heel skin crack? It stings just walking on it at work in my steel tip boots. Is there a good "runners" liquid skin or a good tape to keep it from getting worse during the run?
That sounds quite painful and uncomfortable! My first advice would be not to over-do it during the race. However, one thing that you can start to do now is to use Aloe Vera gel, but not the type that comes in bottles at the grocery store for sunburn. It's a wonderful antiseptic and it heals skin issues. You can either rub the gel of the plant (just snip off a leaf) over your skin or if you have a Whole Foods (or a similar store) near you you can purchase a small bottle of whole-leaf aloe gel. Make sure to continue to apply moisturizer (maybe for sensitive skin) and to wear socks at night in addition to the aloe.
I will say though, that if the problem persists, you should also go to see a doctor but you can try the aloe first.
I've had cracked heals and toes off and on for decades now; whenever I get a crack I simply rub a dollop of petroleum jelly onto the area; during the day I tape a band-aid over the area, and at night I just wear an old pair of socks to bed. Within a few hours the skin has softened up enough to eliminate the discomfort; yes the crack is still there, but I don't feel it at all.
With me, it's a build-up of dead skin on the heels and balls that cause them to split. The dead skin isn't flexible and when it splits, the healthy skin underneath splits as well. If left untreated, it gradually gets worse until the splits start to bleed, etc.
I take a medium grade sandpaper and lightly sand to remove the dead skin. Once that's done, I apply a moisturizer to the healthy skin underneath to soften it up.
Once you remove the dead skin, the splits heal pretty fast, within a day or two.
BTW, they sell foot soaks that'll soften the skin as well. Soak your feet in the solution for about 20 minutes and the dead skin will practically rub off with just hand pressure.
