I am selling this item because I no longer have a use for it and would like to pass it on to someone who can. *There was a defect, and I received a brand new replacement from the manufacturer. I have not tried them on even once since they arrived. WAVE PROPHECY STRAP Listed on the Mizuno official website for 20,900 yen (tax included) Size: 27.5cm Purchased in May 2025, so it's the upgraded latest version. Thank you for looking. The following is a product description: This model is inspired by sprint spikes. Newly released with an updated strap. The upper design of the WAVE PROPHECY STRAP is reminiscent of track and field sprint spikes. The distinctive upper design and pattern are based on Mizuno's sprint spike fitting theory, with a strap structure that tightens key points and allows for one-action fitting control. It also features an adjustment tape for fine-tuning and enhanced fitting. The heel has a high-elasticity mesh that wraps the foot and a heel counter for a secure hold and stable design. The main feature is the Wave Prophecy sole, uniquely developed by Mizuno. It uses a hollow infinity-structure wave plate, minimizing the cause of midsole deterioration. It's a sole that combines stability and unique cushioning, as well as "functional beauty."
