On Cloudswift US size 8, Japanese size 26cm Used for casual wear. It's in good condition in my opinion, but please check the photos and understand that it's a used item before purchasing. It will be shipped in a box from another manufacturer. Product Description: It seems they struggled quite a bit to achieve the contradictory characteristics of cushioning and rebound in a single material. However, without compromise, they continued their unique research, and as a result, they completed "Helion," a material worthy of being called a super foam, which is highly resilient, lightweight, durable, and resistant to temperature changes. Helion is a new material developed in-house by On and is used in the CloudTec®︎ part. On has already fused cushioning and rebound from the structural aspect of its unique CloudTec technology, and this time, they succeeded in doing so from the material aspect with the newly developed Helion, making it even stronger. It protects your legs from the impact of the road and converts the impact of landing into forward propulsion. The new Cloudswift model, equipped with Helion, is surprisingly soft, gentle, and yet a nimble performance shoe. "Swift" shoes that fully support road running in a shining city. The Helion™ super foam in the shoes delivers the best performance in urban running. I received a purchase once, but there was a cancellation request, so I am listing it again. Thank you.
