My handmade mukluks have a hard wax bottom that mysteriously melted in places and won't harden. What do I do? - handmade mukluks

I have a few Mukluks craft with traditional fund wax lasts longer than a rubber sole. I went for the winter, but has these areas seems strange that the melted wax. It was hot against something that will just store in a box in my closet for the summer. They expressed "point" does not harden and can not use because they are very catchy.
As the wax to harden to use it again?
