Description

Field of the Invention The present item relates to an item of footwear, more particularly to an item of footwear housing an item of interest in the sole thereof. Background to the Invention Crystal healing is an alternative-medicine practice that uses semiprecious stones and crystals such as quartz, agate, amethyst or opal. Practitioners of crystal healing believe that such semiprecious stones and crystals can boost low energy, prevent bad energy, release blocked energy, and transform a body's aura. In some cases crystals are placed on different parts of the body, often corresponding to chakras; in other cases crystals are placed around the body in an attempt to construct an energy grid, which is purported to surround the body with healing energy. It is also believed that such crystals operate more effectively when they are located close to or in contact with the earth, and are simultaneously located close to or in contact with the body. In particular the Earth Star Chakra (Vasundhara) represents the body’s bond and connection with the planet Earth, and is located outside of the body below the soles of a person’s foot. There is therefore a belief that a crystal placed between the earth and the person’s foot is better able to transmit energy to and from this chakra in particular, especially where there are no barriers therebetween.

When the second sealing portion 26b is located in position as illustrated in Figure 5 the surface 37b of flange 30b mates with the surface 37a of flange 30a of the first sealing portion 26a, as illustrated in Figure 16, to form the sealing member 24. In one alternative the first and second sealing portions 26a, 26b are permanently connected, in another alternative the first and second sealing portions 26a, 26b are detachably connected. In the embodiment illustrated a midsole unit 56 is provided. Figure 6 illustrates a view of the upper surface 58 of midsole unit 56 and Figure 7 illustrates a view of the lower surface 60 of midsole unit 56. The midsole unit 56 is provided with an aperture 62 the aperture corresponds to the size of the main body of the second sealing portion 26b and flange of sealing member 24 such that when in position the midsole unit 56 is in position the second sealing portion 26b extends through aperture 62. However, the midsole unit 56 need not be provided in all alternatives, and in an alternative no midsole unit is provided.
