A shoe comprising:

• a plate;
• a shaft extending from the plate, wherein the shaft is externally and helically threaded, wherein the shaft and the plate are a single monolithic piece from form a same material;
• and a heel containing a barrel therein, wherein the barrel is internally and helically threaded, wherein the barrel includes a lower closed end portion and an upper open end portion, wherein the heel is removably coupled to the plate based on the shaft helically fastening to the barrel from the upper open end portion to the lower closed end portion as the barrel is perpendicular to a flat surface on which the heel stands when walking and the plate extends over the heel and the barrel;
• an arch that extends from the plate in a direction away from the shaft, wherein the arch and the plate form a single continuous piece formed from a same material.

A method comprising receiving a shoe and a heel wherein at least one of:

• the shoe comprises a plate containing a barrel therein, wherein the barrel is internally threaded, wherein the barrel includes a lower open end portion and an upper closed end portion;
• a heel having a top portion;
• a shaft extending from the heel, wherein the top portion extends around the shaft, wherein the shaft is externally threaded, wherein the heel is removably coupled to the plate based on the shaft fastening to the barrel from the lower open end portion to the upper closed end portion as the top portion faces the barrel and the plate and as the barrel faces the top portion;
• an arch that extends from the plate in a direction away from the barrel, wherein the arch and the plate form a single continuous piece formed from a same material, or
• the shoe comprises a plate;
• a shaft extending from the plate, wherein the shaft is externally and helically threaded, wherein the shaft and the plate are a single monolithic piece from form a same material;
• and a heel containing a barrel therein, wherein the barrel is internally and helically threaded, wherein the barrel includes a lower closed end portion and an upper open end portion, wherein the heel is removably coupled to the plate based on the shaft helically fastening to the barrel from the upper open end portion to the lower closed end portion as the barrel is perpendicular to a flat surface on which the heel stands when walking and the plate extends over the heel and the barrel;
• an arch that extends from the plate in a direction away from the shaft, wherein the arch and the plate form a single continuous piece formed from a same material.
