【How to Choose the Right Size】
When selecting the appropriate size, measure the length of your foot from the longest toe to the heel while barefoot. Compare this measurement to the size chart below to determine the correct size.

• S Size: 21.0cm – 23.0cm (8.3" – 9.1")
• SM Size: 23.0cm – 24.0cm (9.1" – 9.4")
• M Size: 24.0cm – 25.0cm (9.4" – 9.8")
• L Size: 25.0cm – 26.0cm (9.8" – 10.2")
• LL Size: 26.0cm – 27.0cm (10.2" – 10.6")
• LLL Size: 27.0cm – 28.0cm (10.6" – 11.0")
• 4L Size: 28.0cm – 30.0cm (11.0" – 11.8")

For individuals with larger body size or foot size, selecting a larger size is necessary. However, as the size increases, the impact at contact and the load on the body also tend to increase.

For this reason, when performing intense or high-impact movements, please use with caution and allow your body to adapt gradually.

We recommend choosing and using the product in accordance with your physical condition and capability.
