TECHNICAL FIELD

The present invention relates to a footwear, in particular, a footwear that could be used for covering the foot securely with respect to a sole structure of the footwear, and also to aid in support and stability of our foot.

BACKGROUND OF THE INVENTION

Walking and running on bare feet when at sea, in the water or on the beach are common practice. Walking and running barefoot is considered as one of the more real dangers, as it can cause dirty objects to pierce the skin of your foot and cause not only pain, but possibly even infection. Such wounds can be caused by sharp objects lying on the beach.

A regular shoe is simply not suitable for the water and a regular fin is simply not suitable for land. Regular shoes are slippery when walking on a wet surface or in the water, and possibly result in injuries to wearers of such shoes. Therefore, beach shoes or water shoes are designed for both walking on the beach and moving in the water, as typically shoes are made of strong and durable rubber to protect feet from sharp objects such as spiny shells, horse mussels and broken sea shells and sharp, rough rocks but can also serve as protection against stings from various creatures.

However, the beach shoe is not suitable to be used for walking on hot sand, shopping esplanades near the beach area, or even heading back to the hotel or resort.

Hence, a suitable footwear is proposed for those who want to wear their shoes from home and go all the way to the beach and into the sea without taking off their shoes. The proposed footwear is also useful for hiking around bodies of water where you would also like to swim, or hiking and crossing a lake without the need of changing beach shoes to normal shoes and continue hiking on the other side. SUMMARY OF THE INVENTION

One embodiment of the present invention relating to the footwear or shoe comprises; a top portion and bottom portion attached to form a foot receiving cavity, characterized in that the bottom portion having at least an outer-sole portion attached to at least one inner-sole portion, wherein the outer-sole portion has a fin-like extension stretched beyond the foot receiving cavity in parallel projection, in which that width of the fin-like extension has smaller or same width or length of the outer-sole portion, such that the outer-sole portion with the fin-like extension is suitable to be used for walking and swimming.

The outer-sole portion is positioned beneath the foot receiving cavity and, one part or of the toes portion, the outer-sole portion, has a fin-like extension stretched beyond the foot receiving cavity in parallel projection, like a swim fin, swim fins or diving fins. The footwear or shoe includes a heel section and a forefoot section, in which the outer-sole portion having the fin-like extension stretched beyond the forefoot section.

The outer-sole portion and the fin-like extension have a tread pattern that provides ground friction forces or improve the traction of the existing shoe. The fin-like extension is a single piece formed from the outer-sole portion, in which the width of the fin-like extension has smaller or same width or length of the outer-sole portion, such that the outer-sole portion with the fin-like extension is suitable to be used for walking and swimming.

The outer-sole portion is made of strong and durable rubber to protect feet from sharp objects such as spiny shells, horse mussels and broken sea shells, etc. The outer- sole portion also has good floor-grip to prevent slipping during walking or climbing on submerged rocks.

Another embodiment of the present invention relates to an outer-sole of a footwear or shoe, wherein the outer-sole portion has a swimfin-like extension stretched beyond the foot receiving cavity in parallel projection, in which that width of the fin-like extension has smaller or same width or length of the outer-sole portion, such that the outer-sole portion with the swimfin -like extension is suitable to be used for walking and swimming. The outer-sole portion is a skid-proof structure. The present footwear or shoe is suitable for those who want to wear their shoes from home and go all the way to the beach and into the sea without taking off their shoes. It is also very useful for hiking around bodies of water, swimming, hiking at a lake or crossing a lake and hiking on the other side.

The present footwear or shoe is suitable for beach goers, as the footwear can be used for walking on the hot sand and going into the sea without taking off their shoe and come up at any point of the shore and walk back to their spot without looking for a replacement of shoes or sandals.
