Help young athletes push themselves even further with the boys' GEL-CUMULUS™ 21 GS performance road running shoe by ASICS. With a full-length EVA midsole and rearfoot GEL™ technology, this shoe boasts premium levels of shock absorption and energised cushioning underfoot for a smooth, comfortable ride.
We've added GUIDANCE LINE™ technology to ensure young feet feel stable and supported, even over long distances, while the internal heel counter holds the foot in position to reduce the risk of twisting and torsion.
We know kids can be tough on shoes, so we've added our highly resistant rubber AHAR™ compound to those areas of the outsole that take on the most impact and strain. Added support comes from a durable rubber heel plug to ensure the shoe will withstand long-term wear, even from the most dedicated young runners.
The ORTHOLITE™ sockliner provides an additional layer of cushioning comfort, while the flexible mesh upper means the feet will feel cool and ventilated, no matter how far they go. With the GEL-CUMULUS™ 21 GS model in their training kit, kids will have the confidence to tackle any distance in comfort.
