Keen KW400 Review – A Shoe Designed Just for Walking?

Last Updated: November 24, 2024

By Noel Paine  

With runners and walkers doing different things with their legs and feet, it makes sense that the shoes for each would be a bit different. It seems however that most people out walking are wearing running shoes. This may be due to the fact that there are lots of runners and running shoe stores, and fewer walking specific shoes and stores.

I am a runner, walker and competitive racewalker (taking walking to its limit). This is my review of the new Keen walking-specific KW400 walking shoe.

This shoe seems to follow the trend of the running shoe industry, using plate technology of some sort to reinforce the midsole, enhance the rocker of the shoe and look to try and improve walking/running efficiency.

“Walking takes longer…than any other known form of locomotion except crawling. Thus it stretches time and prolongs life. Life is already too short to waste on speed.” - Edward Abbey

I have always been very active, even as a kid and have loved moving and exploring. I like walking, hiking and exploring trails, running on the road, trails etc. and now as a Masters athlete I stumbled across racewalking. As a walker and racewalker, I was intrigued and excited to get my hands on this new KEEN shoe.

How is the Fit and Feel?

The shoe feels substantial and is a snug fit around your heel and ankle with a well padded heel collar and tongue. The offset lacing, I did not really notice affecting the fit, but you can notice visually. The shoe does not come in widths and is not overly wide, but I did not notice it feeling tight. For my size 12 foot, it fit true to size.

  • Snug to get into but comfortable.
  • Feels solidly off the ground and well cushioned.
  • You feel a hump, almost arch support in the middle of the shoe, odd but not uncomfortable.
  • The outsole looks and feels durable and has great grip
  • When you step in and move your foot you can really feel the rocker.

What is it Like to Walk in the Keen KW400?

It has a distinct feel and the most rocker I have felt in almost any shoe including some of the running super shoes. The hump and support in the shoe is as close to an arch support as I have ever felt in a shoe. Comfortable, different and interesting is as I would describe it. It might take some people a while to get used to.

I think the shoe that comes close to the feel of the KW400, would be a HOKA running shoe with its substantial midsole and decent rocker.

Who Should Try it?

I would suggest someone who walks a lot and wants to get the most out of their active walking to try this shoe. For a very casual walker or someone older, the extra rocker in the shoe etc. might be too much and maybe not appreciated.

Difference Between Walking and Running

Walking and running are different. One of the key differences is that running involves a continuous gait with both feet off the ground at some point, while walking has one foot on the ground at all times.

  • CARDIO: Running usually provides a more intense cardiovascular workout than casual walking. Racewalking (walking fast with a different walking technique) can provide an intense cardio workout.
  • INJURY: Walking has a lower risk of injury due to the fact the foot hits the ground with less impact each foot fall.
  • CALORIES: Running burns more calories per minute than walking. For a person who weighs 160 pounds, walking at a pace of 3.5 miles per hour (about 17minutes for mile)(just under 11 minutes per kilometre) for 30 minutes burns about 156 calories, while running at 6 mph for the same time burns about 356 calories. Running can burn almost double the number of calories as walking for the same time.
  • RACEWALKING CALORIES: Racewalking can burn more calories than regular walking and can come close to burning as much as running when done at a high pace/speed.
  • BIOMECHANICS: Although similar running and walking require the feet and legs to move differently.

Difference Between Walking and Running Shoes

Running shoes are made for the impact of running (3-4 times your body weight when your foot hits the ground). They are also made to flex where you need to during a run. Walking shoes in general can be firmer and the cushioning can sometimes be firmer. A lot of people use running shoes with no problems for walking, but it does not work the other way around.

Fitting Tips

The same general tips you use for fitting a running shoe apply for walking shoes. Make sure the shoe is comfortable, fits snug not tight or sloppy and has enough toe room. It is a good idea to measure your feet each time you get a new shoe and to get advice from a knowledgeable shoe person.
