Product Details

Run further than you thought possible in the GEL-NIMBUS® 21 running shoe for women by ASICS - packed full of plush cushioning and special technologies to respond to your natural stride. Now with a vibrant new design, it will get you pumped to unleash your inner runner, even when it's grey outside. The GEL-NIMBUS® 21 shoe is fitted with our I.G.S® (Impact Guidance System) technology: a construction technique that allows the shoe to respond to your natural gait. TRUSSTIC SYSTEM® technology provides added stability. The upper is made from Jacquard mesh and will fit snugly, allowing air to flow and keep the foot fresh as you run and run. Our famous GEL® technology in the front and rear sole gives you energized cushioning in the form of shock-absorbing silicone for heavy-impact activity. Meanwhile, FLYTEFOAM® Propel technology in the midsole offers excellent bounce and toe-off. This lightweight foam formulation has a special high-energy return elastomer helping to put a spring in your step. Gain even more bounce with our SpEVA insole, which also helps the shoe last. To ensure a great fit, there's an external heel counter which holds your heel firmly, keeping you comfortable as you pound the miles. And we've added an AHARPLUS™ heel plug on the outsole to help you be able to run as long as you want. This ASICS High Abrasion Resistance Rubber is a tough rubber compound used to reduce excessive wear. All of this lets the shoe take the strain so you can concentrate on what matters: your breathing and pace.


Pronation is part of the natural movement of the human body and refers to the way your foot rolls inward for impact distribution upon landing. Understanding your pronation type can help you find a comfortable running shoe. The GEL-NIMBUS 21 is made for Underpronation and Neutral.
  • Under
  • Neutral
  • Over


  • Foot Type

    High arches
  • Push Off

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

Rated 5 out of 5 by from Excellent shoe It is a beautiful supportive shoe.  I love that the toe is NOT black!  Unfortunately it did not accommodate my orthotics because the heel/ankle area is too shallow.  Previous versions of this shoe were fine - so I'm disappointed.  Wish ASICS would use this color scheme for a GT-2000 model.

Rated 5 out of 5 by from Holy ASICS these are great! I’m new to Asics. Tired of shoes that didn’t fit right, weren’t really designed for running and just general overall poor quality (Nike). I started looking at ASICS. I have always loved the fun colors! Have always heard how great they are. Now I wish I made the switch sooner! So impressed, day one went for a quick little 5k and they felt amazing! I’m never going back! Lol I run inside mostly and have an overpronounced run. These worked great. No ankle pain, I felt bouncy and fast. My run was a breeze! The cushion around the ankle is just right, this is always a weird spot for me. The soles are the perfect combination of cushion while allowing me to feel the ground beneath. I purchased a pair of these in a 7( I’m usually a 6.5) and the Excite( in a 6.5), I plan to use these when I focused more on just the run for the day & the Excite when it’s more of a training day with a mix of run/weights.

Rated 5 out of 5 by from Excellent pair of shoes I have been wearing the Asics gel nimbis since the 9 came out. I love these shoes, comfortable and the quality is A plus!. This years shoe is particularly comfortable. I have brought 3 pair of these shoes this year. The fit is excellent. There is plenty of space in the toe area and do not squeeze your toes together.

Rated 5 out of 5 by from ASICS Gel Nimbus- perfect shoe is back! This review is for the ASICS Gel Nimbus 21 (Black / Coral) Thank you ASICS for bringing back a good shoe. I have been an ASICS Nimbus fan for years. The 15, 16, and 17 were the best. It seems from 18 to 20, the quality, support, comfort, and color choices began to decline in this shoe. I was so happy to put my foot back into a perfect shoe with ASICS Nimbus 21. This shoe is perfect for those with high arches, small ankles or ankles with needed support, and a slightly wider toe box. The colors in this one are awesome. I am looking forward to the 22 and hopeful for the same support, comfort and quality. Thank you ASICS. You got this one right! Please keep it up!

Rated 5 out of 5 by from Second pair This is my second pair of gel-nimbus 21. I have many other asics shoes from previous years. I like that the shoe is narrow as I have a narrow foot. It has decent arch support.
