Excellent footbed! Arch support is
"Excellent footbed! Arch support is perfect!"

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.

"Excellent footbed! Arch support is perfect!"
"I’ve struggled with foot pain for years, but my podiatrist recommended these sandals, and they’ve made a world of difference."
"Love these this is my second pair and I will continuing ordering them as long as they are available. The first pair I ordered because my doctor told me to wear shoes with support after being diagnosed with plantar fasciitis. After reading reviews I took a chance and ordered my first pair. Let me tell you it was the best pair of flip flops I ever used. Great arch support and I wear them all day long doing errands walking the dog for long walks and my feet never hurt. The base is solid not rubbery and bendable like other flip flops which tend to make you trip. Don’t hesitate to buy these. You won’t regret. I tell everyone about this product. Come to think of it the company should send me a free pair for all the business I sent their way lol!"
"I love these shoes! I had so many issues with my plantar fasciitis and I work a job where I stand for eight hours with only one 30 minute break and no options to sit down in between. These shoes have been a godsend. I have a sparkly white and a plain white I have a flat black and a sparkly black I have two silver and now I just ordered a navy. Of all the shoes I have ordered and tried these seem to be the absolute best with the comfort and standing or walking they are not slippery even if they get wet they fit my foot very good and they are super comfortable. I love the indentation for your toes and for your heel and how it is protected as well as the wonderful art support that’s not too strong. The price is always great! You really can’t beat it. I have shared the link of my shoes with many people. I am so thrilled with these shoes. The shoes are not too loose and not too tight. There’s a little bit of stretch to them but not too much. I can wear these shoes at work every day. I do swap out one pair for another because of having to stand so long at work but they function perfectly for what I need. I highly recommend them. I live in South Florida so I pretty much wear flip-flops 12 months out of the year almost every single day and these are the ones that are on my feet 99% of the time."
"Runs small but if you go one size larger the fit is comfortable enough. I chose size 11 which is one size larger than normal for me. Most often size 10 is loose on me in sandals. These fit more like a 9.5 fit. The footbed is firmer than I expected but should soften up over time.I have plantar fasciitis on the right heel and sensitive toes so this style is so far comfortable and doesn’t irritate my feet. I just got them yesterday so hopefully I’ll be able to wear them regularly."
"The sandals are comfortable and fit perfectly from the minute I put them on. They are fashionable and at the same time support my feet so I don't experience any pain."
"I purchased a navy blue pair. At a glance they look black. The comfort is a 5 star"
"Great foot pad but way too narrow"
"I love these. First of all theyre red!! They are really comfortable and thank you for letting me know to order a size larger. They fit perfectly."
"Very comfortable great arch support and they look really nice on!"
