The Asics Gel-Cumulus 20 is new and improved! You can expect a better fit with a wider toe box and for those that have had issues with the big toe rubbing a hole in the upper, the toe box is higher as well. The outsole has been redesigned for full ground contact with fewer components. The midsole has also been upgraded to FlyteFoam Propel & FlyteFoam Lyte for improved cushioning comfort. These improvements have also made this update noticeably lighter. The Asics Gel-Cumulus 20 is a daily trainer built with cushion and comfort for the neutral runner.
