The standard (medium) width for women is B, while the standard width for men is D. Shoe boxes and labels will only identify widths other than standard. Within the shoes, wide and narrow widths are identified on the label, underneath the tongue — ie. T005N(2E).

When is additional width needed?
Visible stretching or bulging on the outsides of forefoot materials is a good indicator that additional width may be needed. These sizes are available in many of our Running and Training shoes. In some cases, men can wear women’s styles to achieve a narrow fit and women can wear men’s to get a wide. If this is needed, please use the references above to determine comparable size lengths. Please note that the differences of width between narrow, standard, wide, and extra wide are usually only a couple millimeters and are proportional to the size of the shoe. Most additional width will be found in the forefoot.

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. ASICS GEL-NIMBUS 21 is made for under, neutral.

Underpronation (Supination)
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.
Push Off
The pressure is on smaller toes on outside of foot.
Considered Injuries
Plantar fasciitis, Shin splints, Ankle strain.
Foot Type
High arches
Neutral
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.
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.
Foot Type
Normal size arches

Rated 3 out of 5 by from comfortable but not durable I've had these for a couple months now, I'm just getting back into the swing of running regularly. I have run less than 70 miles on the road in these and the tread is almost gone in some areas. Down to the foam on my right foot. I started noticing the wear on rainy runs because i would slip on my push off. I could have received a defective pair, or I could just be hard on my shoes. I will be trying out other brands in the future after pretty much exclusively running in Asics for years.

Rated 4 out of 5 by from Great running shoe, I walk 3-5 miles a day and these shoes are the most comfortable I have worn and will not stray from ASICS. The fit is true the size and I like how the heal is a bit narrower to allow for a nice tight fit. The shoe laces are the WORST. ASICS feels they need to put elastic shoe laces in their shoes and after a month of walking the shoe laces are twice the length they started out as.

Rated 5 out of 5 by from Beautiful Shoe Black, grey and silver come together in great styling. I was a runner for 40 years but had to quit for knee and back problems.and Now use running shoes for walking because they are so comfortable.

Rated 1 out of 5 by from Not what they used to be I have been wearing the Nimbus since the 15. I am finding the 21 to be the worst of them, the level of comfort on these shoes is horrible. Guess im back to square one of looking.

Rated 5 out of 5 by from Love the shoe I’ve had these shoes for a couple weeks now and they are just what I expect from Asics. I am on my feet all day and these shoes really help me get through the day. Super comfortable! Will definitely continue to buy Asics shoes.

Rated 5 out of 5 by from Awesome These were a gift for my husband on our 11th anniversary and he totally loves them. He tells me that they are extremely comfortable. He has them on all the time. He already told me he needs a new pair. Lol

Rated 3 out of 5 by from Great Shoes Very comfortable shoes. The insole, laces, and the shoe in general is very soft. The yellow color sticks out. They are a little snug in the front, but I didn't have any problems running. The length is perfect. Feet felt pretty good after running, a little ankle pain but overall good shoes.
