This is the cushioned-neutral running shoe that you have been waiting for — the soft, plush feel of the traditional Nimbus minus the weight. The one-piece FLYTEFOAM midsole uses sustainable nano fibers (They are made out of sugar cane.) for increased durability with fantastic energy return. This shoe is soft and responsive. Sustainability continues with the upper — made almost entirely of recycled materials. The GEL-Nimbus Lite takes the number one feature of the original Nimbus — great cushioning — and incorporates it into a sleek, lightweight shoe that you will have lots of fun running in.
