The women's Nimbus is Asics's superb shock absorbent long distance road running shoe for the neutral runner. New features include a FF Blast + Eco midsole - which is Asics' lightest, softest and most sustainable foam. The new Rearfoot PureGel, in the top layer of the midsole, is 65% softer than the visible Gel in its predecessor to offer you a super soft landing.
