Inspired by the natural phenomenon of the Northern Lights, this special seasonal pack radiates energy. GEL-Cumulus® celebrates its 20th anniversary with premium technology and a refined design that offers optimal support and comfort for runners of all levels. A FlyteFoam® midsole teams up with rearfoot GEL® cushioning for a smooth, lightweight ride that maintains full contact with the ground. Its jacquard mesh upper elevates the styling and forms to your foot for a fit that feels customized just for you.
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-Cumulus 20 SP is made for Underpronation and Neutral.
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.
Normal size arches
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.
I.G.S® (Impact Guidance System) Technology
ASICS design philosophy that employs linked componentry to enhance the foot's natural gait from heel strike to toe-off.
FlyteFoam® Propel Technology
ASICS energetic foam formulation that provides supreme bounce thanks to a unique elastomer compound.
FlyteFoam® Midsole Technology
Our FlyteFoam® technology provides exceptional bounce back and responsiveness no matter the distance, utilizing organic super fibers to help reduce packing out that traditionally happens with softer, low density foams.
ASICS FluidRide® midsole provides the ultimate combination of bounce back and cushioning properties with reduced weight and exceptional durability.

The use of seamless materials reduces the potential for irritation and friction caused by traditional stitches and seams.
Independently placed eyelets disperse lace tension, creating a customized fitting environment and enhanced upper comfort.

Cumulus 20 spShoes are very hard and run half size small. They are very narrow. I could not walk on them so I sent them back and after more than 2 weeks I still need to hear about the refund.

Size runs small.I have consistently worn an 8 in ASICS for years. I bought an 8.5 to allow room for an insert. Should have gotten a 9. I need more room with these. The shoe is narrow but fits my foot fine. However if you do not have narrow feet, this might be an issue.
