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

• 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.
