Great buy
Ordered a pair for work where I am standing all day as a surgical tech. The first pair came defective I say that because there was a bump where the little toes are on one foot and it hurt while wearing them I reached out to Amazon and they were quickly replaced with a new pair. I’ve had them for about two months. They are amazing. A little on the big side but it’s perfect because sometimes I wear thick socks so my feet don’t get cold and I still have some wiggle room. I love how comfortable they are, I was scared of the holes on the side but they have great breathability and nothing has gotten into my shoes. They’re honestly better then my other OR shoes that cost way more then these. I love them and recommend them if you’re in need of some comfy standing shoes that also happen to look nice

Most comfortable crocs ever
Size: 13 Women/11 Men
Color: Black/Black
Most comfortable pair of crocs I’ve ever purchased or worn. They do run big but nonetheless I would highly recommend these. I normally wear 11 in my crocs but definitely needed a 10 instead.

DOG GROOMER!!!
Size: 7 Women/5 Men
Color: Black/Black
I am a dog groomer and was looking for a crock type shoe that was squishy but didn’t have holes on the top to keep hair and water out of my shoes, but that had holes on the sides for ventilation. After seeing these I looked other places but found nothing comparable. So I grabbed these. They are perfect! I do deal with planter fasciitis so time will tell if they work, but so far are very comfy. I do wish they had a strap on the back. But am so thankful to find these! Of course I had to add some cute crock charms! Everyone said to size down. I wear a 8-9 in regular crocks and a 8 1/2 in tennis shoes, so I ordered a 7 in these and they are perfect! I do more standing than walking as a dog groomer and I think the LiteRide sole will be super comfy! 10/10 recommend!

What A Welcome Surprise of Comfort
Size: 13 Women/11 Men
Color: Black/Black
These clogs are more stylish in person than they appear to be in photos. They are extremely comfortable and are perfectly sized. The height is ideal so that your pant legs don’t get walked on by your heels. These definitely have more inner sole cushion and comfort than even the regular Crocs clogs do; which are already comfortable. If you like those you’ll really enjoy wearing these — even for hours at a time on hard flooring like at Costo or the grocery store.

They are extremely roomy even with Sockwell socks on
I wanted to love these. The details suggest sizing down. I decided to go with my size. As far as length they were accurate, just a little room but for me that was fine. But the width is wide. Still not a huge deal breaker as I stand all day so the width allowed for swelling. But by the 3rd day I could feel tender areas but when I took them off just standing by my locker my feet hurt and were very tender in places, I put my home shoes on (I work in surgery and Crocs were for work) my feet ached the rest of the evening. I wanted these to work sadly they are not for me. As I said I work in surgery, my roll has me standing for long periods usually unable to move around or shift my weight so I need support at the same time cushion.
