FIELD OF INVENTION
The invention generally relates to a field of footwear and more particularly to soles of a footwear.
BACKGROUND
There are a variety of shoes available for variety of purposes like running, walking, trekking, playing, dancing etc. Purchasing different shoes for different applications results in both higher expenditure as well as more space occupancy at home. One of the major element that differentiates shoes based on the application is the sole. For e.g. Trekking Shoes have Rubber Sole with deep lugs/indentations to give secure footing on rocky surfaces. Soccer Shoes will have a hard sole with spikes/studs to provide increased traction on grass fields. Running/Walking shoes have a rubber sole with flat minimal depth patterns. Professional shoes have a hard sole with minimal depth patterns. A single pair of shoe that can be used for all kinds of applications and surfaces can prove to be very useful and cost saving.
Hence there is a need for shoes that can adapt itself based on the terrain or surface conditions where a person uses them.
SUMMARY OF THE INVENTION
According to an exemplary embodiment of the invention, an adaptable shoe is disclosed. The adaptable shoe may include an arrangement for automatically selecting at least one or more sole faces. The arrangement for automatically selecting the sole face may comprise of a

plurality of sensors. According to an embodiment, the adaptable shoe 100 may comprise of at least one motion sensor. The motion sensor may measure the walking or running speed of the user and may send the information to a controller. According to another embodiment, the adaptable shoe may comprise of at least one pressure sensor. The pressure sensor may measure the pressure being applied on the shoe and send the information to a controller. According to yet another embodiment, the adaptable shoe may comprise of at least one moisture sensor. The moisture sensor may detect the wetness on the floor and send the information to the controller. According to an embodiment, the adaptable shoe may comprise of a combination of one or more motion sensor, pressure sensor and moisture sensor. According to an embodiment, based on the information received by the sensors, the controller may arrange an appropriate sole face to engage on the ground. The proposed invention may enable using a single pair of shoes to adapt itself based on the different types of terrains.

According to an embodiment, the sole 102 may comprise of at least one or more compartments 104. According to an embodiment, each compartment 104 may have a sole hub 106, such that each sole hub 106 may have a plurality of sole faces 108. According to an embodiment, the sole faces 108 may include sole with spikes, studs, deep patterns, less patterns etc. The sole faces 108 may be arranged on the sole hub 106 in such a way that only one sole face 108 may engage the ground surface from one compartment 104 at one time. According to an embodiment, a mechanism may be provided to engage the sole face 108 on the ground surface.
Figure 2 illustrates a schematic diagram of an adaptable shoe 100 according to an exemplary embodiment of the invention. The adaptable shoe 100 may include an arrangement for automatically selecting 112 at least one or more sole faces 108 based on the terrain of the surface. The arrangement for automatically selecting 112 the sole faces 108 may include a plurality of sensors. According to an embodiment, the adaptable shoe 100 may comprise of a

motion/speed sensor 114. The motion sensor 114 may measure the walking or running speed of the user wearing the adaptable shoe 100. The motion sensor 114 may send the measured information to a controller 120. According to an embodiment, the controller 120 may select the appropriate sole face 108 based on the information received from the motion sensor 114. According to another embodiment, the adaptable shoe 100 may comprise of a pressure sensor 116. The pressure sensor 116 may measure the pressure being applied on the adaptable shoe 100 while the user is wearing the adaptable shoe 100. The pressure sensor 116 may send the pressure information to the controller 120. According to an embodiment, the controller 120 may select the appropriate sole face 108 based on the information received from the pressure sensor 116. According to yet another embodiment, the adaptable shoe 100 may comprise of a moisture sensor 118. The moisture sensor 118 may measure the wetness on the surface and send the information to the controller 120. According to an embodiment the controller 120 may select the appropriate sole face 108 based on the information received from the moisture sensor 118. According to an embodiment, the adaptable shoe 100 may further comprise of a combination of at least one or more of the motion sensor 114, the pressure sensor 116 or the moisture sensor 118. According to an embodiment, the combination of sensors in the adaptable shoe 100 may include the motion sensor 114 and the pressure sensor 116. According to another embodiment, the combination of sensors in the adaptable shoe 100 may include the pressure sensor 116 and the moisture sensor 118. According to yet another embodiment, the combination of sensors in the adaptable shoe 100 may include the motion sensor 114 and the moisture sensor 118. According to yet another embodiment, the combination of sensors in the adaptable shoe 100 may include all of the motion sensor 114, the pressure sensor 116 and the moisture sensor 118. According to an embodiment, the adaptable shoe 100 may further comprise of more sensors apart from the motion sensor 114, the pressure sensor 116 and the moisture sensor 118 such as a temperature sensor, GPS sensor etc. Each sensor may be placed

at a different location on the shoe sole 102. According to an embodiment, the sensors may be placed at the front part of the adaptable shoe 100. According to another embodiment, the sensors may be placed at the centre part of the adaptable shoe 100. According to yet another embodiment, the sensors may be placed at the rear part of the adaptable shoe 100. According to yet another embodiment, the sensors may be placed on all the front, centre and rear part of the adaptable shoe 100.
