So I have always had this phenomenon that takes place with Flip-Flops. My foot migrates to one side and crushes the edge of the sole. Because of this, they are always twisted on my feet (See Pic for crushed area). The Corkers how ever seem to have a "Concave or pocket ( What ever you want to call it ) that looks like it should keep your heal and foot landing in one spot. Have not really worn the Corkers that much but the Duck Bill model does not do this (Too Flat??). The Corkers also look like they will have more cushion : ]

Gumbies Corkers are my favorite flip-flops! The shape conforms to my foot, the outsole is grippy and durable, and the cotton straps are soft and comfortable while still being strong. The footbed is comfortable and I love that the cork layer is a natural material, it's antimicrobial, doesn't pick up smells easily and is easily washable.
I had a pair of them years ago and when it was finally time to replace them, the Corker was out of stock. So, I've tried other styles....but I saw the Corker back earlier this year and got a Black pair. I just ordered the Khaki colored ones to have a couple options because I couldn't let these slip away again!

Light and airy, strong and well-fitting, comfortable and easy to take on a plane...to the beach, which I will be doing!

These are the best most comfortable Flip Flops I have ever worn, no hot spots, no blistering, work rest or play these are superb.

I think they are great , comfy and they are going to last

Light, unique, attractive

Very comfy, can walk for miles!

Very thin bottoms provided little to no cushioning. Too bad as the grippy bottoms were great.

They were so uncomfortable I had to give them away.

Fit is perfect!!!! Super comfy

I live in flip flops 8-9 months a year, and I normally get a new pair each year because I wear them out. I got tired of my feet sweating and smelling from the normal foam that comes on the bigger brands, so I set out to find something that had natural materials like cork for the footbed. I found these and decided to give them a try. LOVE THEM. My feet stay way cooler, they’re totally comfortable, look great, and now I want to buy these for my wife and kids. Ditch the foam! Your feet absorb all the toxins from them…go natural! They’re basically like Birkenstocks without looking like Birkenstocks.

Too slim for me no padding compaired to hey dudes which I returned these for as well as now im frustrated because my refund isn't back and ive sent my pair back over a week ago!!

Fit is true to size. Comfortable on day one with no “breaking in” period.

Extremely comfortable, zero sweat with the fabulous cork sole... love the cork!

I love them, they are more comfortable then I thought they would

The Corker is a very comfortable flip-flop. Along with the Cairns, the Corker is the first Gumbies I have tried. The straps were a little tight when I first put on the Corker flip-flops, but they loosened up very quickly. I really like the comfort of the cork footbed.

I just wish Gumbies made a sandal and slide with a cork footbed.

The Corker runs true-to-size.

Great product and very comfortable

Comfortable, but the Gumbies turned my heel black unfortunately!
