【Material & Craftsmanship】

Each component of ippon blade 1000 (zen) is crafted with precision, using traditional Japanese materials known for their durability, flexibility, and comfort:

• Hanao (Strap): Sanada Himo (真田紐) – A tightly woven cotton or silk fabric, historically used in samurai armor and traditional accessories for its strength and resilience.

• Dai (Platform): Paulownia (桐) – A lightweight yet durable wood, often used in traditional Japanese footwear and furniture due to its shock-absorbing properties and moisture resistance.

• Ha (Tooth): Magnolia (朴) – A robust and slightly elastic wood, providing optimal balance and grip while maintaining a natural feel underfoot.


【Important Notice】

Orders will take approximately one month from confirmation to delivery.
Please place your order with this in mind.


【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: up to 23.5 cm (up to 9.3”)
• M Size: 23.5 cm – 25.0 cm (9.3” – 9.8”)
• L Size: 25.0 cm – 26.0 cm (9.8” – 10.2”)
• LL Size: 26.0 cm – 27.0 cm (10.2” – 10.6”)
• LLL Size: 27.0 cm – 28.5 cm (10.6” – 11.2”)
• 4L Size: 28.5 cm – 30.0 cm (11.2” – 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.
