Nice
Size: 10.5, Color: Black White
True fit. Not the hard back. Not easy to slide into without using your finger. Comfortable at a good price.

VERY comfortable shoe, great for wearing on long days.
Size: 11, Color: All Black
VERY comfortable shoe for the price!! Just as comfortable as my name brand shoes, Nike, ASICS and Adidas. Not sure how long these will last only have had them for a short time, I will update my review at a later date for that!
It does run pretty wide, I have a wide forefoot it was large on me. I recommend ordering at least a 1/2 -full size down if you are a woman wearing this shoe. I normally wear a 10.5 men's, I ordered an 11, it was large on me. Good amount of stretch to the shoe as well, good and breathable.
I did retrofit an arch support insert and replaced the he laces with elastic ones. Made the shoe EXTREMELY easy to wear and put on hands free (when needed). I have to say it's great for a variety of activities, as well. So fa wore to work, vacation walking and running errands.

Exactly the shoes I've been looking for...
Size: 11, Color: All Black
I attend a lot of concerts and an annual 5 day music festival in Baltimore. Needless to say it is a lot of walking and standing on concrete. Of course my feet, knees and legs absorb a lot of punishment especially at 61 years young. I looked around on Amazon before attending this year in hopes to find shoes that may help at a reasonable cost. Let me tell you I just returned from this years fest and all I can say is buying these Feethit Sneakers was the best decision I made. Super comfortable, didn't require a lot of break in, lightweight, flexible with fantastic support. Everything I had hoped to find and can't believe all the boxes were checked with one show. 5 days of walking and standing and could have easily done 5 more. Thanks so much Feethit !!!!
