PURPOSE: The sole of a shoe is provided to have movable protrusions without the connection to an outsole by attaching a portion of protrusions which are placed on a sole to a soft midsole without integrating with a hard outsole, thereby improving the mobility and flexibility of the sole. CONSTITUTION: The sole of a shoe include a midsole (10) which is located at the bottom of an upper (12), one or a plurality of protrusions (20) which protrude from the bottom (11) of the midsole, an outsole (30) which includes a top (31) which is attached to the bottom of the midsole and one or a plurality of holes (32) through which the protrusions penetrate, and one or a plurality of outsole pieces (40) which are attached to the bottom of each protrusion. A sole manufacturing method includes the following steps. The protrusions which protrude from the bottom of the midsole penetrate through the holes which are formed inside the outsole. The bottom of the midsole is attached to the top of the outsole. The outsole pieces are attached to the bottom of the protrusions which penetrate through the holes. |
