- Replaceable sole members 104 in accordance with the present invention may be utilized for multi-terrain shoes with different soles for different terrains; for example, trail, street and/or sidewalk, running track, treadmill, indoor court, outdoor court, grass, or any other terrain.
- sole members 104 may be various types of soles, such as racing soles, training soles, and extra support soles. Use of separate sole members 104 allows for a user to customize the sole properties, e.g., to compensate for pronation or to provide more or less traction in different areas of the foot, for example, in forefoot, mid-foot and/or rear-foot locations.
- the present footwear 100 is ideally suited for those wearers who participate in a number of different indoor and outdoor activities or sports, allowing the same uppers to be used with a number of different removable lower soles, thereby eliminating the need to purchase multiple pairs of expensive shoes.
- Footwear 100 of the present disclosure with interchangeable sole members 104 are particularly valuable for persons who desire variety in footwear and are limited by considerations of economy.
- One pair of main body 102 may be used with a number of interchangeable sole members 104 , thereby affording a wide variety in footwear apparel at a cost of little more than the price of one or two pairs of conventional footwear.
- Footwear 100 with interchangeable sole members 104 are also desirable in instances where storage or packing space is at a premium.
- a traveler may need pairs of shoes with different types of soles for performing varying activities (like, walking, hiking, running, etc.), which ordinarily would fill an entire suitcase.
- varying activities like, walking, hiking, running, etc.
- substantial packing space may be saved, because the compressible interchangeable sole members 104 fit into a comparatively small area.
- the present footwear 100 allows the wearer to quickly and easily change the soles on his or her shoes to meet specific needs. Also, as the sole member 104 is disposed inside the main body 102 , the sole member 104 cannot separate from the main body 102 during the use of the footwear 100 .
