Shoe with spikes

A shoe, comprising:

• a shoe body including a bottom surface relative to the ground;
• an accommodation seat including a bottom wall attached to the bottom surface, a surrounding wall extending from the bottom wall toward the ground, and a chamber defined by the bottom wall and the surrounding wall;
• at least one moving plate disposed in the chamber and being controlled to move between a first position and a second position, the at least one moving plate including a plurality of push members;
• an operation member inserted through the surrounding wall;
• a transmission module disposed in the chamber, the transmission module including an operation gear connected with the operation member and at least one moving unit corresponding to the at least one moving plate, the at least one moving unit including a control gear meshing with the operation gear and a cam connected to an axle of the control gear, the cam being rotated to touch and move the at least one moving plate;
• at least one spring connected to the at least one moving plate;
• a plurality of posts, each post having a first end fixed to the bottom wall and an opposing second end extending toward the ground;
• a plurality of spikes respectively fixed to the second ends of the posts and extending out of the chamber;
• a shoe plate including a shoe plate body, a push surface formed on the shoe plate body, a plurality of upright through holes formed in the shoe plate body and a plurality of grooves formed on the push surface, the posts being inserted through the upright through holes, respectively, the shoe plate being movably disposed in the accommodation seat;
• wherein responsive to the operation member being moved, the operation member drives the operation gear to rotate, and the operation gear rotates the control gear of the at least one moving unit, and the control gear rotates the cam for controlling an extension portion of the cam to either push and lean against the at least one moving plate or remain spaced with respect to the at least one moving plate;
• wherein responsive to the extension portion of the cam being rotated to lean against the at least one moving plate, the at least one moving plate is secured in one of the first position or the second position and the at least one spring is deformed;
• wherein responsive to the extension portion of the cam being rotated to remain spaced with respect to the at least one moving plate, the at least one spring generates a horizontal restoring force to move the at least one moving plate to the other of the first position or the second position;
• wherein responsive to the at least one moving plate being in the first position, the shoe plate body is in a retracted position and the spikes protrude out of the shoe plate body relative to the ground, and the push members are accommodated in the grooves, respectively;
• and
• wherein responsive to the at least one moving plate being moved from the first position to the second position, the push members push the shoe plate body and are moved out of the grooves to lean against the push surface, the shoe plate body is thereby moved toward the ground to an extended position, and the spikes are accommodated in the upright through holes, respectively, and do not protrude out of the shoe plate body relative to the ground;
• and
• at least one return spring, the at least one return spring having an inner diameter for insertion of a corresponding one of the posts, the at least one return spring being positioned between the shoe plate body and a corresponding one of the spikes, wherein responsive to the at least one moving plate being moved from the first position to the second position, the shoe plate body is pushed from the retracted position to the extended position to compress the at least one return spring, the at least one return spring being deformed, the at least one return spring being stopped by the corresponding spike to not separate from the corresponding post, and the spikes being accommodated in the upright through holes, respectively;
• wherein responsive to the at least one moving plate being moved from the second position to the first position, the shoe plate is not pressed and thereby does not compress the at least one return spring, and the at least one return spring generating a vertical restoring force to push the shoe plate body to the retracted position.
