A shock absorbent heel for a shoe includes: a heel seat portion configured so as to have a top surface configured to be attachable to a bottom portion of a shoe upper; a mid-heel portion formed of a cushioning material; a bottom heel portion, the mid heel portion being sandwiched between the heel seat portion and the bottom heel portion when the shock absorbent heel is in an assembled state; and a dowel. The dowel is arranged in a vertically extending dowel chamber in the shock absorbent heel. The dowel is configured to pass along vertically shocks caused by contact of the shock absorbent heel with the ground so that at least a portion of the shock is absorbed by the cushioning material of the mid heel portion.

The present invention discloses a height adjustable modular heel (2) for use in a shoe, comprises a heel body (22) having a first end detachably attached to a heel base (21) that is affixed to the shoe and a second end detachably attached with a heel cap (23) to protect the heel body (22) from wear and tear, wherein the heel body (22) is formed by identical heel body pieces (22A) that are detachably attached together in a stacking manner to form a desired height for the heel (2) depending on a number of the heel body pieces (22A) stacked, and wherein the heel body pieces (22A) are interchangeable and stackable in any sequence to allow for customization of the heel height, characterised in that the heel (2), assembled by the heel base (21), the heel body (22) and the heel cap (23), forms an arc of a predetermined radius to achieve same or similar level of ergonomics at different heights.

A device for protecting a heel of a shoe includes a body including an upper end and a lower end, a flexible material positioned along a portion of an outer edge of the body, and an attachment mechanism positioned at the upper end of the body.
