Find Your Perfect KEEN Fit.

At KEEN, we've always believed feet work best when they're given the freedom to be feet. That's one of the reasons why roomy toe boxes have always been at the heart of our footwear. When your toes have space to spread naturally, your feet can move, flex and support you the way they're designed to. Rather than squeezing them into a narrow shape, we create footwear that gives them room to do what they do best – whether you're heading out on a hike, spending all day on your feet, or simply exploring your everyday adventures.

Of course, not every foot is shaped the same way. That's why we offer a choice of fit options, from our signature Original Wide-Fit to our more streamlined Contour Fit and our roomiest Extra Wide-Fit. So whether you prefer a spacious feel, a more secure fit, or need extra width, there's a KEEN fit designed for you.

FOOT MEASURING TIPS / SIZE

How should I measure my foot?

Did you know that your foot size can change as an adult? We recommend measuring your feet every year. All you need is a piece of paper, ruler, and pencil. Here we go: 

1. Place a blank A4 piece of paper on the floor with the shorter edge touching a wall.

2. Stand on the paper with your heel slightly touching the wall.

3. Мark the end of the longest toe on the paper (you might need help so you can make an accurate straight down mark, at the tip of the toe.

4. Do the same for the other foot.

5. Measure from the wall (or edge of the paper) to the mark in centimeters.

6. Take the larger of the two measurements and match it up on our size chart to find your shoe size.

7. Enjoy that just-right fit feeling!

Foot measuring tips:- Measure with your preferred (average) sock on. If you plan on wearing a below or above average thick sock, please take that into considerations when purchasing the shoe or boot. Since feet always swell during the day, it is a good idea to measure and try shoes on later in the day, when your feet are at their largest.- Feet typically get bigger with age. Try to measure your feet every year.

What size should I buy?

After you have measured your foot, here are some tips for finding the right fit:


- Your left and right feet may differ in length or width. Be sure to
measure and try shoes on both feet, and always buy shoes to fit your
larger foot.


- If your feet seem between sizes, and you cannot decide which size to select, we suggest choosing the larger size. You can adjust for a more personal fit with socks, insoles, or a different lacing pattern.

Note: Because the foot is three-dimensional, any two-dimensional measuring tool, such as a ruler or Brannock device®, can only approximate your shoe size. Manufacturers use different lasts to construct their shoes, and sizing may vary accordingly. For best results, visit your local KEEN Retailer to get measured and try on the footwear.

How does sizing work for KEEN kids shoes?

Our kids' sizing is broken down into 3 categories:

Toddler - Sizes UK. 3-7

Little Kids - Sizes UK. 7-12

Big Kids - Sizes U.K 12-5

After big kids size UK 5, the next size up is UK women's size 6.

Why does KEEN sizing differ from other brands' sizing?

There is no footwear industry standard for shoe size. At KEEN, we list shoe sizes in centimetres so you can easily compare sizing with other brands.
