You could apply K-Y jelly on your heels to prevent chafing
Sports enthusiasts, this hack is for you. If you enjoy running, you have probably dealt with sore heels due to your sneakers rubbing against your feet. In these cases, you should first check that your running shoes fit properly and that you haven’t accidentally purchased a pair that fits too small.
After verifying that your shoe size isn’t the cause of the issue, you should coat your heels with a layer of K-Y jelly before heading for your morning run. Another option is covering the irritated skin and blisters with a small amount of petroleum jelly.
