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. | Features. Engineered double jacquard.
