Retail price: 20,000 yen Currently hard to obtain. The quality was quite good, but I'm selling it because I've switched from track events to marathon and ultra-marathon, and I no longer have a use for it. I used it very carefully, but it doesn't have insoles. You can either prepare some high-rebound insoles or use it as is. It was a bit tight, so I used it without anything inside. I ran about 10 kilometers on the track with it, and it's in very good condition.
