I purchased my first pair of ON shoes six or seven years ago, and they were awesome: great cushioning, arch support, very light weight. (Second pair was also great.) In the past few years I have been disappointed with their quality. The arch support is missing, and you can see a visible difference in how the shoes are made. The older models have a separate piece of molding around the inner edges to support the foot and arch. Totally missing in newer models. Regretfully I am going to be looking for something different.

I was hesitant to buy based on other reviews but I am so glad I did. For me they are true to size. I dont have wide feet so maybe if you do you should consider sizing up, but for me I am wearing the size I normally wear. They are very comfortable and stylish and I am happy with my purchase. I highly recommend

Absolutely beautiful shoe if it didn’t come in dirty. I worked twelve hours that day and was excited for my new shoes only to receive them used. In the ON cloud shoes I’m a 5 1/2 and they fit true to size. Let’s do better Zappos please!

In comparison to the On Cloud Runner 2 and On Cloud X 4, the On Cloud X 4 AD has a bit less cushion feel to it. It also feels like the tongue and heel tab hit a bit higher on the ankle; however, it is a comfortable shoe and find it good for cardio training.

The perfect everyday runaround shoe. Great for long walks, going to the gym and so much more! Can be machine washed and dries quickly. I love this shoe so much I just bought my 2nd pair!

I did not feel like I was walking on clouds. I felt like I was walking barefoot on the pavement. There was little to no cushion. I tested these on my walking pad and barely got 1/3 of a mile before the bottom of my left foot was burning. I felt that they run a little snug and on the narrow size. The shoe itself was cute. I liked the colors but they weren’t comfortable.

Very disappointed. And my feet are covered in bloody blisters and are in pain. I am not sure what they have done to the design but it’s a no-go.

Its ok but i didn't like the t-shirt like rim around the ankle-seems flimsy as opposed to a rolled edge.
