The present invention relates to an inline skate and an ice skate (hereinafter referred to as skate) provided with a shoe fixing structure, and more specifically, between the upper surface of the skate frame and the upper ankle protector of the upper surface of the frame to enable the detachable shoe. By combining the fixing plate, inserting the shoe inside the shoe fixing plate and fixing the shoe through the combination of the upper fixing strap and the ankle protector cuff, so that ordinary shoes having various sizes and shapes can be removed and enjoyed skating. It relates to a skate provided with a shoe fixing structure.

As is well known, conventional skates are not shown, but a boot body for inserting and fixing the foot into the boot, a blade or wheel support attached to the bottom of the boot body, and a blade or wheel support built in the It consists of a blade or a plurality of wheels fixed by bearings and binding plates to move the boot body from the ground.

Such a conventional skate was flawed that the walking function was weaker than the excellent driving performance, and this disadvantage is that when the user wants to climb stairs or travel a relatively long distance while wearing the skate, the user has to change to normal shoes. There were a lot of inconveniences, such as the inconvenience is that if you carefully climb the stairs there is a damage of equipment and flooring, and the risk of slipping on the stairs during the movement has a very high possibility of a safety accident.

In addition, the skate is equipped with a blade or a bearing for increasing or decreasing the friction of the wheel between the blade or the wheel and the wheel support, when the skate is worn in sand or soil, the blade or equipment is damaged or bearing There was a problem that sand could be inserted and damaged.

In addition, the conventional skate has the disadvantage that the boot itself is very heavy, it is inconvenient to carry, and also inconvenient to store.

Therefore, in recent years, heels shoes have been released to compensate for these disadvantages. However, the heelless shoe is to be equipped with a single roller on the rear end of the general sneakers to lift the front gum of the shoe to allow a certain distance using the roller.

In addition, unlike ordinary skates, it was impossible to accelerate the ground by pushing the ground with high-heeled shoes. The Hillis shoes were just shoes that ran to the front of the shoe, accelerated, and then slipped some distance using the rollers.

In addition, the conventional removable skates and heels shoes have no structure for absorbing shocks or integrated into the ground, so the boots of the skates must be reinforced to prevent damage to the ankles. Since the shape of the boot has a structure that can completely cover the ankle, there is a problem that its own weight is very heavy and it is inconvenient to carry, and even when the length of the boot is long, when it hits an obstacle or is shocked against the ground, the ankle or There was a high risk of knee damage.

In addition, such a conventional skate is provided with a plurality of fastening means from the upper surface of the shoe of the boot to the front end of the boot, and after the foot is inserted into the boot, the foot and the ankle are accommodated so that the boot can be completely fixed to the foot and the ankle. If you fall down while driving, you can protect your feet and ankles, so it takes a lot of time to fasten. Due to these problems, it is necessary to lift off the skates that contain boots even when moving toilets or climbing stairs. It was very inconvenient. At this time, because the boots are fixed to the skates, even if you take off the skates to go to the bathroom or to climb the stairs, you have to go up the stairs with bare feet or prepare separate shoes again. Store or carry heavy skate gear There was.
