Asics Tennis Shoes GEL-RESOLUTION Ⅹ OC, 23.5 cm, brand new, unused. Surface type: Omni clay court. I bought two pairs new, and after trying one, I've decided to switch to shoes that are a bit softer and lighter. This item is the other pair, which has been kept unused. It's a popular product, and it's often out of stock, so if you're looking for a pair, how about it? *Please refrain from price negotiations. Below is the manufacturer's product description: Tennis shoes for omni and clay courts, pursuing stability that supports dynamic lateral movements. Provides advanced stability and comfort for players who prefer to control the game from the baseline. The DYNAWALL resin part in the midsole extends from the heel to the forefoot to enhance stability during lateral movements, and a window is provided in the little toe area to improve comfort, supporting lateral stability and footwork. In addition, FF BLAST PLUS ECO, which is used for the first time in tennis shoes, is adopted in the heel part of the midsole. FLYTEFOAM is used in the forefoot, and by using a 2-piece structure of different materials, comfort and cushioning at the time of landing have been updated while maintaining stability. DYNALACING, which is linked to the shoelaces, improves the fit between the upper and the foot during high-intensity movements. Also, the ankle cut, which is higher only on the inside, prevents the ankle from twisting beyond the range of motion when stepping sideways.
