Studies indicate that a lack of arch support can lead to problems such as fallen arches and inversion of the ankle joint. Additionally, poor gait patterns and a toe-clenching stride may cause conditions such as patellar tendinitis and inflammation of the plantar fat pad, subsequently triggering knee pain.

Moreover, the design of traditional slippers may restrict the movement of the hip flexor muscles, leading to overuse of the quadriceps and increasing the risk of issues like patellar tendinitis.

The advantage of arch support design is that it offers stable support, which helps maintain normal foot biomechanics, reducing stress on the feet and related joints. This, in turn, lowers the risk of foot complications and abnormal gait patterns.
