From step-in to take-off, the GEL-451 is designed to cut down on time. From the first moments of slipping your foot into the seamless upper, to tightening the shoe with the quick fasting Boa closure system – which will quickly and easily adapt to your foot at a simple turn of the dial – it is sure to get you out of transition area and onto the road faster than before. Rear foot ASICS GEL cushioning and Magic Sole outsole will provide more bounce back while still providing protection under foot. A perforated sock liner optimises moisture drainage, allowing your feet to stay dry and comfortable. Say goodbye to your old personal records and say hello to speed.
