When my son was little he went barefoot in bark mulch and got a huge number of splinters sticking straight out of the bottom of his little feet. My quick thinking neighbor ran home and grabbed a pot of wax used to remove unwanted hair. She heated it to warm and spread it all over the bottoms of his feet. When it cooled, we peeled it off. It removed the vast majority of the splinters. I was able to remove the rest with watchmaker tweezers, which I've used many times to pull out thorns and splinters.
