Excellent fit and comfort for OR work!
These shoes are fantastic! I rarely write reviews but had to for these. As a male, I found they fit true to size, which can sometimes be hit or miss when ordering online. I’ve tried several other brand named clog-style shoes, but my heel would always slip out. These have a more narrow heel design that keeps my foot secure. I work in the OR and needed something easy to clean and built to last. The cushioning is incredible and it feels like I'm walking on clouds. The chunky design gives them a cool look as well. These are by far my favorite clog-style shoes. If you're on the fence, I highly recommend purchasing them.
Looks a little clunky but are super comfortable!
I was specifically looking for clogs that had a back and most on the market do not so I somehow found these during my search. It's a relatively new brand but I liked this specific speckled color as well as the fact that they're a sustainable company. There were no reviews anywhere so I was a little wary but still purchased. I couldn't find them being sold anywhere else except at REI or the actual brand site (sold out anyway) so I purchased them from REI. For some reason REI did not carry Women's 6 which is my normal size in almost all shoe brands so I opted to try the Women's 7 which actually fit pretty well. Slightly loose but they don't fall off my feet because they're surpringly light and the shoe hole where my foot goes into isn't too large. I did not find any sweating issues probably because it's a little loose on me and there are ventilation holes on the inner side of the shoe. It comes with these super comfortable insoles which makes it feel like I'm walking on a cloud! I'm petite so the fact that the insoles adds a little to my height was a bonus. They do look a little doofy/clunky but I'm willing to deal with the look because they are so comfortable. Overall, a 5/5! I am a healthcare worker and am on my feet many hours each work day.
Best nursing shoes ever
I never write reviews but had to with these shoes. These are PHENOMENAL. I’m a nurse and work 12 hours shifts on my feet and have tried every pair of shoes you can think of. Crocs, dansko, calzuro, brooks, on cloud, you name it. None of them hold a candle to these. I get excited to wear these to work. It’s been a few months and it still feels like I’m walking on clouds. My feet used to throb after my shifts and now they don’t hurt at all (even after 3 12 hour shifts in a row) I have been telling everyone at work about these. These shoes have a fan for life. Do yourself a favor and buy them. For around 60 bucks, you get happy feet.
Comfy but runs small.
Comfy but runs small. I have a women’s size 9 and my toes seem to feel like they are touching the front of the shoe regularly. Buy 1 size up. And wear thicker socks.
