● Item This is a listing for the NIKE ReactX Infinity Run 4. These shoes offer the best balance of cushioning, responsiveness, and stability. As NIKE claims, they help prevent injuries, making you less tired and allowing for a bouncy stride that lasts. The stretchy Flyknit upper provides excellent hold, and the full rubber outsole is designed to be non-slip and highly durable. They have a bright and unusual color scheme that uplifts your mood, and a playful design typical of NIKE. The size is 27.5cm. ● Condition I purchased these shoes new from a sporting goods store and used them for jogging to maintain my fitness for about 3 months. While there is some visible dirt due to the white base, the running distance is estimated to be around 50km, so there is still no noticeable wear on the soles. I am selling them now because I no longer use them. I usually wear a 26.5cm size, but these shoes were a bit narrow, so I went up 1cm and they fit perfectly. However, the Flyknit upper provides excellent hold, and there was no discomfort from going up 1cm. Please understand that these are used items and may have some dirt from normal use. ● Price Reduction The price includes shipping, so I am generally not considering price reductions. ● Notes The price includes shipping. Instant purchase without comments is OK. Please refrain from cancellations due to personal reasons after purchase. I will ship them in simple packaging to reduce shipping costs.
