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. The highly resistant AHAR® rubber compound reduces wear at key impact areas of the outsole, making this a performance running shoe that you can really count on as you look to reach new levels. 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.
Pronation
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 21 is made for Underpronation and Neutral.

Underpronation
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.
Neutral

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.

Gel CummulusI usually buy the women's Asics 9D in a different style, but they were out, so I tried these in the comparable size. I bought them for the arch support noted on this style as i have a very high arch. I am very pleased with the arch support and toe box on these shoes. The heel is a bit wider than the women's shoe so a bit looser than I would like. I have to say i like the arch support better than Brooks. Overall, the support has made a noticeable difference in how my feet feel at the end of the day (nursing).

I've been wearing them for years...I love these shoes; roomy toe-box & comfortable cushion. Each pair seems to last between 300 to 400 miles. I change my shoes every 3 months. I've been wearing them for years. They seemed a little bigger than usual this last time I purchased them. I buy a half size up because my feet swell when I run. I will buy them again. If they continue to run big - I'll just size down the following purchase.

Good marathon training shoeGood shoe for high mileage running. I run 2 Marathons a year in this shoe, training 35-45 miles a week. I go through 2 pair a year. The shoe holds up very well, plenty of cushion. A little lighter than the Nimbus, but still good cushioning for a lot of miles.

Great shoe for neutral and underpronationThis is a very comfortable shoe, and it is very well made. I do recommend that if you know your feet are prone to overpronate and/or know you have a low arch maybe try the Gel-Kayano line or the GT-2000 line. The Gel-Cumulus line is definitely a great, quality all-around shoe for me, but my shins do hurt during and after long runs. Still love the shoes, will keep them, but I will mostly train and use the elliptical in them.

Great ShoesI live my Asics. Light weight, cushy, comfortable, and cool. I generally hit 10 plus miles a day on my work days and the Asics make that a lot more bearable. Ever since I switched to Asics a few years back that is all I wear.

Solid, Well-Balanced Running ShoeI don't know that much about running shoes but got this line recommended to me at the fancy shoe store many generations ago. This is my third version. It's a solid running shoe with a medium amount of cushion and tends to be pretty durable. It's not a shoe that makes me want to go preaching in the streets about it but it's a reliable choice.
