Comfortable at First, But Did Not Last Long
Size: 9.5, Color: Cs05 White
I used these Feethit men’s slip on running shoes for about six months, and my experience was a bit mixed.
Starting with the positives, they are pretty comfortable right out of the box. They are lightweight and easy to slip on, which makes them great for quick trips or casual everyday wear. The fit was true to size for me, maybe even a little on the loose side, which I did not mind for a relaxed feel.
However, the durability just was not there. After about six months, I started to notice wear and tear, and eventually I got a tear in the sole right under my heel. That made them really uncomfortable to walk in, especially for longer periods. Once that happened, it was basically game over for using them regularly.
Because of that, I would not recommend these for heavy use, workouts, or long days on your feet. They seem better suited for light, occasional wear rather than something you rely on daily.
Overall, they are comfortable and easy to wear at first, but they do not hold up over time. If you are looking for something long lasting, you may want to look at other options.

Won’t Fit No Matter What
Size: 9.5, Color: Cs05 White, Size: 9.5, Color: Cs05 White
These shoes don’t stretch so I was unable to get my foot in the shoe. They are my size, but the opening has no stretch so you can’t get your foot in the shoe. I tried several different ways and then realized even though the shoe is the correct size, the opening was too small. They made the opening for the shoe probably the same size on all shoes, so unless you have kids feet you won’t even be able to slide them on. I’ve never had a shoe I couldn’t get on. I’ve worn Sketchers no problem. This is design flaw and I highly recommend you don’t buy!

Really comfortable!!!
Size: 11, Color: New Black05
These tennis shoes are so comfortable!!!
I would recommend anybody to get these, especially if you do a lot of walking they’re very light but have a good heal support and the soul is nice and soft and cushy..
They’re also so cute. I got the blue ones and red also.

Great Fit, Lightweight, and Totally Quiet
Size: 11, Color: New Black05
Great fit and very comfortable once you pick the right size. Lightweight, breathable, and completely silent on hard floors. No squeaks or “suction” sounds like some reviews claimed. Normal packaging, normal opening, no issues at all. Excellent value for the price.
