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.

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.
Go further than you thought possible with the men's GEL-CUMULUS® 21 performance road running shoe by ASICS. Designed to cushion and support your feet over long distances, this shoe boasts FLYTEFOAM® Propel technology for excellent bounce and energy. The combination of rear and forefoot GEL® technology means you benefit from a level of shock absorption not available in many other shoes, while GUIDANCE LINE™ technology enhances your gait efficiency and the internal heel counter holds your foot in position no matter how far you go. Further support comes from I.G.S® (Impact Guidance System) technology which enhances your natural gait as you move, and the EVA sockliner that molds to the shape of your feet for added comfort.

Ventilation is provided by the engineered jacquard mesh upper, so you can rest assured that your feet will remain cool even when your run heats up. Reflective details on the outside of the shoe ensure you'll be noticed, even at lower light levels. With this exciting new design of the GEL-CUMULUS® 21 shoe in your running bag, you'll be able to take on those extra miles in comfort and style.

Great Walking Shoe
I walk over 35 miles a week. I start walking about two years ago at the beginning of the Covid pandemic. Over the two years, I have never had a blister and my feet feel great.

Perfect Balance of Cushioning and Responsiveness
I hav run in many versions of Cumulus shoes and the Cumulus 21 is my favorite. I thought the Cumulus 20 was my favorite until the 21 version came out with improved balance of medium cushioning and responsiveness, and were even more comfortable right from the start. I have bought numerous pairs of the Cumulus 21 as the redesign of the 22 version is too soft and less responsive. The balance of the 21s are clearly superior

Great running shoe for Under-pronators
This is a great running shoe for under-pronators. Comfortable, relatively light, ample toe box, great outside sole wear. Only downside I had was an eyelet splitting.
