The present invention provides a method of making a foaming member with heterogeneous foaming layers. The first step is adding a foaming agent and an accelerator to a first material, which is a flexible material, and a second material, which is a non-flexible material, respectively, and then pressing and stirring the first material and the second material respectively for well mix. The second steps is pressing the first material and the second material respectively to form a first material piece and a second material piece. The third step is stacking the first material piece and the second material piece to form a stack. The fourth steps is vulcanizing the stack in a high pressure and high temperature environment to bond the first material piece and the second material piece together firmly; and the last step is releasing pressure on the stack to get a foaming member.
