  2A Narrow
Narrow B Standard
Standard D Wide
Wide 2E Extra Wide
Extra Wide 4E  

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.

Product Details

Move your mind with the GEL-KAYANOâ„¢ 31 shoe.

The GEL-KAYANOâ„¢ 31 focuses on delivering holistic, adaptive stability with premium comfort underfoot. It is ideal for runners looking for a combination of moderate support and high-cushioning during their run.

4D GUIDANCE SYSTEMâ„¢ is found in the midsole. This new technology helps to steady your stride on your run.

PureGELâ„¢ technology improves softness and shock absorption to reduce the impact on your joints and keep you running comfortably.

FF BLASTâ„¢ (FLYTE FOAM BLAST) PLUS ECO foam delivers softer landing and energised cushioning to keep you feeling comfortable on harder surfaces.

The new technical engineered upper material provides comfort and a stable fit.

What is the 4D GUIDANCE SYSTEMâ„¢ ?

Developed at the ASICS Institute of Sport Science (ISS) in Japan, there are four key elements that work together to support your run.

- Midsole geometry and design features including a lateral decoupling groove

- Medial convex geometry

- A newly designed lateral guidance line

- The midfoot foam of FF BLASTâ„¢ (FLYTE FOAM BLAST) PLUS ECO that provides comfort for the fatiguing foot.



Width: B standard - STANDARD

A women’s standard shoe width is B, a wide fit is a D and wider again is 2E. In New Zealand the most common shoe width size* for women in running shoes is a D fit.Find out more about widths.

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-KAYANO 31 is made for Overpronation.

HOW YOUR FOOT CONTACTS THE GROUND

The foot lands on outside of heel, then rolls inward (pronates) excessively, transferring weight to inner edge instead of ball of the foot.

Rated 5 out of 5 by Jo Mary from Gel-Kayano 31 I recently had a fracture to the base 5th metatarsal bone in my foot. As part of my recovery returning to the gym and walking I purchased the Gel-Kayano 31 which have provided fantastic cushioning and support.

Rated 3 out of 5 by Hayley S from No as good as the past models Purchased a pair of these for work shoes as I have been wearing them for years, in the previous models, as running/ gym shoes. They have been great for my flat feet with the addition of my orthotics and were my go to shoe to wear if my feet were having a bad day. The 31’s aren’t as good as the ones of the past. They are chunkier, heat my feet up and feel and look like a cheaper product. I have noticed in the past models those made in Vietnam have a better feel and look to them than those made in Indonesia. The 31’s in black are made in Indonesia and have that same feel of cheapness to them which is disappointing given the price paid for them. Please go back to the design of the 29’s and please look into why they are so different when made in different counties. I have 3 pairs of 29’s and the 1 made in Indonesia has the same cheapness as the 31’s also made in Indonesia.
