Use silicone heel cups or arch-supporting insoles to sooth aching heels. If your heels ache, it may be because the back/heel area of your shoe is too hard. It could also be because your shoes do not give your feet enough arch support. Try putting in a silicone heel cup or an arch support insole. Both can be trimmed down to the right size, and have adhesive on the back so that they don't slip around.
