Cloud-Weight Cushion, Built for the Long Haul.
Renowned for its startling cushion-to-weight ratio, the Rincon 4 received a
top-to-bottom makeover to ensure the uber-light softness it's famous for lasts
through even more miles. Upgraded foam provides better rebound while increasing
longevity and works together with rubberized EVA to make each step feel softer
than the last. With a durable podular outsole design and a more foot-hugging fit
than before, this daily trainer is engineered for a longer life without
weighing you down.
