Go further than you ever thought possible with the men's GEL-CUMULUS™ 21 LS performance road running shoe by ASICS. This premium shoe offers supreme bounce and energy thanks to FLYTEFOAM™ Propel and FLYTEFOAM™ Lyte technology, while the combination of rear and forefoot GEL™ technology offers unbeatable levels of shock absorption and cushioning.

The shoe has outstanding support as you move, with I.G.S™ (Impact Guidance System) technology ensuring your feet stay in their natural gait. Extra stability is provided by the internal heel counter and GUIDANCE LINE™ technology, which enhances the efficiency of your stride, giving you the energy you need to take on those extra miles. /p>

If you're running long distances, you need a shoe that's built to last. We've added our highly resistant AHARPLUS™ compound at high impact areas of the outsole to reduce the effects of abrasion and long-term wear.

The GEL-CUMULUS™ 21 LS shoe also features an engineered jacquard mesh for breathability that keeps your feet feeling fresher for longer. Meanwhile, the LITE-SHOW™ technology reflective detailing means you'll always capture attention, even when the light begins to fade. It all adds up to a running shoe you can count on as you look to boost your performance and reach new distances.
