Nice Sandler. Unfortunately can not
"Nice Sandler. Unfortunately can not wear due to a swollen foot from post surgery"

Selecting the perfect shoe size may sometimes seem to be confusing; this can be due to the many conversions between women's and men's sizes or understanding different measurement systems such as European shoe size. Many people search online prior to making a purchase because many different regions have different systems for defining their shoe sizes.
For the purpose of this guide, we will clarify the conversion from size 9 to all other size conversions, as it happens to be one of the most commonly searched for shoe sizes on the internet, so all of the conversion formulas above would also apply to other shoe sizes as well. Therefore, once you understand how each formula/conversion works, you can then apply them to any shoe size with confidence.
Kaizen is a split-toe sandal that manages to look distinctive without sacrificing comfort, which is a rare combo. A vegan leather upper is finished with functional rustic buckles that lock in a secure fit no matter your foot shape. The footbed is built with a deep heel cup and lined in soft vegan suede, so your foot is genuinely cradled rather than just resting on a flat surface, and you can wear these comfortably from morning errands into a night out without needing to switch shoes halfway through. The split-toe silhouette gives it a look you won't find in most standard sandals, and the buckled straps mean you're customizing the fit to your foot, not squeezing your foot to fit the shoe. Your normal size should fit well. If you're a half size or on the wider side, size up a full size (a 7.5 becomes an 8) rather than rounding down. Medium width fit throughout. The Size Chart has exact measurements for anyone checking first.
Choosing Your Size
Order your usual sandal size for the best fit.
Half Sizes or Wide Width
If you wear a half size or have wider feet, size up to the next full size. Ex: If you’re a 7.5, we recommend ordering an 8.

"Nice Sandler. Unfortunately can not wear due to a swollen foot from post surgery"
"Love them. They look great and are true to size. I have a wide foot with high arches and they, the perfect comfort level, and much more affordable than my old sandals"
"These are super cute. Unfortunately they ran small on me & have no comfort experience! But my glittery flips are the best!!"
"I am replacing the pair I wore so much last year because they were my favorite sandals! Felt comfortable the minute I put them on. Definitely love them and got so many compliments on them."
"They are so comfortable and you can just wear them all day. They are inexpensive compared to many other brands offering same support. You might want to go a size up from what you usually wear since they run a little small. They are super lightweight. I love that they offer the foot support that I need when I walk and can use them with everyday wear very functional."

"Im over the moon with my new sandals! These are absolutely the most comfortable shoes Ive ever worn & Im 61. They have perfect arch support & hug the soles of my feet. I have a long narrow footusually wearing 10 narrow so I ordered size 10 & with the adjustable straps they fit perfectly. Too bad summer doesnt last all year but Im in Texas so I know Ill be wearing them a few more months.At the same time I ordered Aerothotics sandals I also ordered a pair from Cushionaire.... I returned them immediately because they did not have even close to the amount of cushion & arch support that Aerothotic sandals have. You will not regret buying these shoes if comfort is important to you."
