Crafted with a re-engineered mesh upper, the Asics Gel-Kayano 27 Tokyo Running Shoes have a great fit that securely hugs and lockdown the foot while providing excellent airflow and breathability so your feet stay cool and well ventilated on long, hot runs. Alongside the premium fit and temperature regulation, the upper has also been finished with large areas of reflective detailing to keep you visible in low lighting conditions. The midsole features a combination of DYNAMIC DUOMAX and SPACE TRUSSTIC technology. These work together to ensure a soft yet stable ride with DYNAMIC DUOMAX supporting the foot and preventing pronating for an efficient stride, alongside the SPACE TRUSSTIC which delivers a smooth transition with added flexibility so the shoe adapts to your foot's natural motion. Additionally, FLYTEFOAM Propel technology gives an energetic, forward propelling toe-off and GEL technology in the front and rear sole enhances underfoot comfort, cushioning impact shocks for a more enjoyable running experience. Perfect for runners looking a running training that offers a good balance of comfort and support and can be used for both training or competitive running.
