This shoe feels unusual. They elevate you an inch or so. The toe and heal are curved up. But they are fabulous for me. I am a flat footed walker and they offer superior support and spring. Great on your joints. They are lightweight. I got them in bright pink which is nutty but they are very fun!

    5.0 out of 5 stars Closest thing to shape ups only better
    Reviewed in the United States on July 2, 2024
    Size: 8Color: Plaza Taupe/BirchVerified Purchase
    I had been looking for a long time for a cute comfortable rocker bottom shoe and this is it.

    PROS: I love the color and look of the shoe. They give me a little extra height. They are very well constructed. The insoles are comfy. I changed the laces to tan no-tie for easy on/off. The rocker bottom kind of propels me along making it more fun to walk. Now if I wear a pair of traditional shoes, they feel dead...just tromping along.

    CONS: They are very narrow, I used a shoe stretcher so they fit my wide foot. Others have commented on this and it would be great if Keen offered wide sizing. The KEEN logo is emblazoned across the front. It's tacky. I wanted to buy the pink style but the logo is even more pronounced on that model.

    Overall, I'm really pleased with this purchase, they were worth every penny and they have become my favorite shoe

    5.0 out of 5 stars Great for high arches
    Reviewed in the United States on February 10, 2025
    Size: 7.5Color: Reef Waters/Evening PrimroseVerified Purchase
    I have really high arches and these shoes have been great. I wear them at work (healthcare worker) and to walk. The support has completely resolved my knee pain. The shoes are a little higher than “normal tennis shoes” and took a little time to get use to. The color is vibrant and pretty true to the pictures. They were easily washed in the washing machine. They are lightweight and won’t keep your feet warm in the winter. But all in all amazing! I will have more colors in the future.

    3.0 out of 5 stars Heel section too wide, toe box too narrow
    Reviewed in the United States on March 9, 2025
    Size: 10Color: Fawn/Peach WhipVerified Purchase
    The pros...true to its definition it is made for those of us who have high arches and after I tried them on I was ecstatic. First time I realized how much pressure other shoes put the arch and how ill fitting my other walking shoes are, these put no pressure on my arch at all. I purchased the Fawn/Peach Whip color hoping they were more pink than peach. I think they are a tad bit pinker, but the color matches the color shown online, I love the color.
    The cons...when I opened the box I think I passed out for a nano second because the smell was like acid. I wear a 9.5, but order up a half size in these type shoes, so a 10. Just standing the door balance was great, but after I started walking my heel slide forward causing my toes to jam in the tow box, which isn't that wide, I'm not going to buy a larger size because for me the design is such that my heel wasn't secured thus the problem wouldn't be eradicated.The material inside the shoes felt like burlap.
    They're an attractive walking shoe and I hoped that they worked! I'm going to see if Keen has other designs that are better suited to my feet.

    1.0 out of 5 stars First pair of Keens I've hated and returned
    Reviewed in the United States on July 20, 2024
    Size: 10Color: TangerineVerified Purchase
    I was excited about the bright neon orange color and that they were for walking. Tried them on and they are narrow, especially compared to Keens signature wide toe box, I had just worse but strike 1.
    2nd I guess I didn't realize how much of a "rocker" style these were, I have high arches and it felt like a round ball was in the middle of my foot. They did have the little extra that comes out from the back of the heel for support but these were not for me! I am used to getting a pair of keens and be able to love the feel and hit the trail or path without break in time. These are not the shoes. I'll stick to the ones I know.

    Missing the wider toe box on the 8.5 so I sized up to a 9
    The 9 arch support did not fit my arch and it as uncomfortable. Besides the fit the size 9 smelled horrible.I aired the shoes in my laundry room and the smell permeated throughout the kitchen.

    2.0 out of 5 stars Comfortable but smelly
    Reviewed in Canada on November 9, 2024
    Size: 8.5Color: Black/Black/BlackVerified Purchase
    The shoes are very comfy but they smell really bad. Very cheap and chemical smelling. I had to put them outside to air them out. This makes wonder how toxic the materials used are.
    I ordered a half size larger based on multiple reviews saying they fit small but I think I would have been fine with my regular size.
    I would have given them 5 stars if it wasn’t for the awful smell.
    UPDATE: been wearing the shoes for 2 weeks. They are so comfortable but that awful chemical, cheap smell is still there. I left them outside for a week and still the smell is there.

    Reviewed in the United Kingdom on January 12, 2025
    Size: 8.5Color: Vapor/Azure BlueVerified Purchase
    Love these walking trainers. Got them in the sale so a good price too. Took in board the reviews and sized up from a 5 to a 6 and they fitted perfectly. I didn’t find the trainers too narrow but maybe that was because I went up a size or just that I don’t have wide feet! They look a bit quirky which I like and most importantly, so incredibly comfortable to walk in. Because they are mainly off white, they get dirty easily and would have loved them to be waterproof but you can’t have everything! Completely worth the reduced price
