Designed For Underpronation Neutral

Underpronation
-
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.

Neutral
-
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.
Run further than you thought possible in the GEL-NIMBUS® 21 running shoe for men by ASICS - packed full of plush cushioning and special technologies to respond to your natural stride. 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. The TRUSSTIC SYSTEM® technology provides added stability so you can focus on pushing yourself further than ever. 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. If the light is dim you'll still be seen thanks to the reflective detail we've included. All of this lets the shoe take the strain so you can concentrate on what matters: your breathing and your pace.

Sub par
The back heel of the shoe is different than any of the ASICS I’ve had before. I have been running for 15 years now , and unfortunately these are not up to standard not sure what to do with these shoes

Excellent for heavier people
I have been using this shoe for about a year now. I am a bit on the heavier side at 215 lbs. I have always looked for shoes that are comfortable and supportive. I have tried different brands and I have to say the Nimbus 21 is the best I have come across. I love how the shoe fits and how the soles are wide at the ball area of my foot. I never liked Nike because of the narrow soles. I always felt like I was going to roll my ankle. I have never experienced this with these shoes. I am just hoping that when its time for a new pair, the later versions of this shoe are just as good.
