AJ4 sole is about 2 cm high, and AJ6 sole is about 3 cm high. On the whole, AJ6 is more effective.

As a basketball shoe, AJ4 should not be too high in sole height in order to ensure wrapping and cushioning performance. As a sports shoe, AJ6 has a slightly hard sole, but it has an air cushion, and the thickness of the sole is between 2.5 and 3 cm, which is more obvious.

When buying height-increasing shoes, you need to consider personal needs and comfort. I suggest you choose the shoes that suit you according to your own needs and preferences.
