Fits well and seems to
"Fits well and seems to be able to walk miles in them without a pain! Glad I got them! Sheila"

Dune blends everyday style with real all-day comfort, no trade-off required. A finely woven vegan leather upper gives it an artisanal touch, and a padded interior guarantees a snug fit that doesn't shift around while you're walking. The ergonomically shaped footbed, with its gentle ripple patterns, enhances grip and supports natural foot alignment, and a durable PU sole makes this a genuinely versatile companion, from a seaside stroll to casual errands around the city. Lightweight midsoles with advanced polyurethane technology help minimize fatigue and discomfort, and a deep heel cup provides real hindfoot support that encourages better posture over time. The anatomic footbed offers excellent arch support and stability for medium arches, so you get a genuinely comfortable, pain-free experience rather than one that just claims to be. Dune's water-friendly design also means you can wear it outdoors in any season without worrying about it. Order what you usually wear. If you're a half size or on the wider side, round up rather than down (a 7.5 becomes an 8). Medium width. The Size Chart has exact measurements if you'd like to confirm.

"I like this so much I bought this pair in three colors!"
"Fit is good. Color goes with a lot of my clothes."
"I have a lot of pretty good flip flops in the $20- $25 range. I saw these and decided to give them a try because I liked the look of them and the good reviews. I chose the Dune Wine color. I will say these are the best ever. The straps look like woven leather and I love the color. Its kind of an Orangie red. Wanted orange but not bright orange and didnt want red as I already have red so this is perfect. They are so well made. Great arch support and the foot bed cradles your heel and keep your foot in place. Great cushioning. The straps are so soft on the underside. You could walk for miles in these in comfort. Lots of great colors to choose from also. I usually wear 8 1/2 W but no W so I went with 9 M and the fit is perfect. They are more expensive but in my opinion worth every dollar. If you can live with the price dont hesitate. The difference between these and the $!5.00 flip flops is night and day. Even a big difference between my $25.00 ones. This is my new go-to brand for flip flops."
"Sooo comfy along with refined stylish look you can wear everywhere! Sizing is perfect! Will buy other colors again!"
"I love these...great look fit and quality!! I get compliments wearing them."
"These sandals are well-made and seem to have enough arch to support those who have plantar fasciitis. However they were too small for me. I consider myself a 10.5 but often buy size 11. My heels extended just beyond the back of the 11s in Dune Black. Since there is not a larger size I must return them. I recommend ordering a size up."
"Love my Aerothotic sandels. They are very comfortable. Unlike other sandals, I can wear them shopping all day & my feet don’t hurt at the end of the day because of the support they provide."
"Wear them everyday. Good support."
"Very comfortable! If you have arch issues these are the sandals for you!"
