Serious Player Only (SPO) drop-in midsole (Support type). Size is 27cm, and the regular price is $44 (approximately 6,500 yen). There is no packaging, but it has never been used, only stepped on with new socks after purchase. I am selling it because I bought it without having shoes that fit the drop-in midsole. It seems to be specialized in shock absorption, with strong arch support, heel support, and cushioning for the ball of the foot. Although it is not exactly the same product, please refer to the following for currently sold products. https://seriousplayeronly.com/ja-jp/collections/spo-drop-in-midsole/products/spo-support-midsole Besides SPO basketball shoes, it may also be usable for Kobe 7, 8, 9, 11, LeBron 11, GT cut 1, 2, Wade, etc., as they also use drop-in midsoles, but I cannot guarantee it, so please check your shoes before purchasing. Here are the product details: ======== The SPO Support Drop-In Midsole allows you to play as you want while firmly supporting your feet. Experience adaptive shock absorption, quick take-off, and ultimate bounce. And above all, experience lateral support that protects you on the court during hard drives and sharp cuts.
