FluidAxis® Midsole Technology
Anatomically correct deep flex grooves have been aligned to the joints of the foot. This innovative construction enables the shoe to recognize, adapt, and respond to the athlete's exact load and positional change from first impact to toe-off.
This lasting material features plush underfoot comfort while providing excellent moisture management and a high level of breathability (Ortholite is a registered trademark of ATP Manufacturing LLC.)
Solyte® Midsole Material
A lighter weight midsole compound than ASICS standard EVA and SpEVA® midsoles. Also features enhanced cushioning and durability.
The use of seamless materials reduces the potential for irritation and friction caused by traditional stitches and seams.
Mimicking the shape of the foot, this anatomically shaped last provides a secure heel fit and an ample toe box that allows the toes to splay.
