Thank you very much for viewing. This is a Nike baseball metal spike, Alpha Huarache Elite, made with breathable mesh material, a Japan-exclusive overseas model. MLB San Diego Padres color. The size is US12.0, and the JPN size is 30.0cm. Nike's spike sizes are generally designed to be smaller and narrower than usual, so we recommend it for those with JPN sizes of 28.0-29.0cm (I usually wear 28.5cm in leather shoes, etc.). I purchased it from the overseas official website, so please note that there is no dedicated box. Since it is a metal type, it cannot be used in games, but I used it 4-5 times in practice, and I don't think there is much feeling of use. However, the sole is metal, so there is some rust, but I don't think it will bother you at all when you wear it. Also, the print on the insole of the right foot is slightly rubbed. This is a used item, so please understand that no claims or returns are accepted. - Brand: NIKE - Color: Brown/Yellow - Model: Baseball Spikes - Features: Breathable mesh material - Sole: Abrasion-resistant rubber sole
