Description

Technical Field

[0001] This application relates to the field of children's daily necessities, and in particular to a children's athletic shoe. Background Technology

[0002] In the field of athletic shoe insole design, the research and development of children's athletic shoe insoles has always been an important topic. During a child's growth, the healthy development of their feet is particularly crucial, and as the part of the shoe that directly contacts the foot, the design of athletic shoe insoles directly affects the comfort and support performance of a child's feet. In existing athletic shoe insole designs, most products focus on overall comfort and cushioning performance, but often neglect the needs of children's feet at specific growth stages, especially the control and correction of rearfoot pronation.

[0003] Hindfoot pronation refers to an excessive outward rotation of the foot during walking or running, which can lead to foot pain, fatigue, and even affect a child's gait and overall posture. To address this issue, specific support and corrective structures need to be incorporated into the design of insoles. However, traditional athletic insoles, especially in the heel area, often use materials with a single hardness, making it difficult to provide sufficient support while also ensuring foot comfort.

The outer shell 1 is a polyurethane potting glue shell body, and the polyurethane potting glue generally has excellent wear resistance and tear resistance, so that the insole is more durable and the service life of the insole is prolonged.

[0040] As shown in Figure 1 and Figure 2 , the arch support 3 is arranged opposite to the arch of the foot, provides necessary support for the foot, helps to relieve the pressure borne by the arch, reduces the fatigue and discomfort of the foot, and the arch support 3 is a polyurethane foaming support. The polyurethane foaming material has a porous structure and can provide appropriate arch support, reduce the pressure on the arch during walking or sports, and reduce the occurrence of the condition of the hindfoot eversion.

[0041] In this embodiment, the arch support 3 has a thickness of 27.6mm to 28.2mm. The arch support 3 with a thickness of 27.6mm to 28.2mm can be used to support a low arch and fill in a normal or high arch. After supporting the arch, it can reduce fatigue and foot pain caused by a low arch and reduce plantar membrane stretching. Furthermore, after filling in the arch, it can increase the contact surface of the sole and evenly distribute the plantar pressure.

[0042] The forefoot support 2 has a gradually varying thickness and is located on one side of the arch support 3. The forefoot support 2 and the arch support 3 are integrally molded, resulting in a more natural transition between the integrally molded forefoot support 2 and arch support 3. This provides a better fit for children's feet, enhances support in the forefoot area, helps distribute pressure, and improves stability during exercise.
