Softer lighter more Nimbus-y. As if it was possible the Nimbus 23 enhances the already cloud-like step-in feel to make the runner or walker both hugged by a love one and on top of a cloud. An improved upper strips down unnecessary material and overlays while making the collar lining material softer to disappear off the foot in the best possible way. ASICS also takes gender preferences with its premier models giving the ladies a softer underfoot feel and an extra 3 mm of stack in the heel. You'll forget you're wearing shoes as you tick away the miles in this new and improved ASICS classic!
