Heel Drop
10 mm
289 g/10.2 oz

Designed For Underpronation Neutral



  • Foot Type

    High arches
  • Push Off

    The pressure is on smaller toes on outside of foot.
  • Considered Injuries

    Plantar fasciitis, shin splints, ankle strain.
  • How your foot contacts the ground

    The outer side of the heel hits the ground at an increased angle with little or no normal pronation, causing a large transmission of shock through the lower leg.


  • Foot Type

    Normal size arches
  • Push Off

    There is even distribution from the front of the foot.
  • Considered Injuries

    Less likely due to effective shock absorption, but neutral runners are not immune to injury.
  • How your foot contacts the ground

    The foot lands on outside of the heel, then rolls inward (pronates) to absorb shock and support body weight.
Get on the road in any weather with the women's GEL-CUMULUS® 21 GT-X performance running shoe by ASICS. GORE-TEX™ fabric ensures water remains on the outside while allowing heat and perspiration to escape. Your feet will feel cool, dry and ventilated, helping you go further than you thought possible. Specially designed for running on hard surfaces, this shoe features rear and forefoot GEL® technology for shock absorption and energised cushioning over long distances. It also boast a springy EVA sockliner and FLYTEFOAM® Propel technology, a lightweight foam formulated with a high-energy return elastomer for unrivalled toe-off and superb bounce with every step. Extra support comes from GUIDANCE LINE™ technology and I.G.S® (Impact Guidance System) technology, which work to enhance your natural gait, helping you to move more efficiently as you clock up the miles. An internal heel counter holds your foot in position for added stability. As well as water-repellent GORE-TEX™ fabric, this shoe also features a moulded snow rubber and AHARPLUS™ heel plug, with a hard-wearing rubber compound at heavy impact areas for abrasion resistance and excellent grip. Plus, the reflective details ensure you'll grab attention even when the light starts to fade. With the GEL-CUMULUS® 21 G-TX model, you can achieve your distance goals no matter what the weather throws at you.

Rated 5 out of 5 by from Nice shoe as expected Very happy with these!! Nice and comfortable, equivalent to all my other permutations of gel cumulus I’ve had through the years. Feel great, nice color, love the turquoise. Walk for miles! Wear all day! they feel great! Best part is my feet don’t get wet walking through the wet grass here In Fall in Washington state . Might be a bit hot for summer, but I have some gel cumulus 22 also brand new for warmer dry days.

Rated 3 out of 5 by from Different feel/fit for Cumulous Larger than expected feel/fit. I always get an 8.5. Not sure if it’s due to the G-TX model that they seem big in the front. ESP when front of foot bends. Least comfortable of all cumulous and I’ve been wearing this type for 10+ years.
