Impressed, bought in every color!
"Most shoes kill my feet but not these!! Walked nearly 10 miles in them while on vacation in Europe and no pain rubbing or blisters. Impressed. Bought them in every color."

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.

"These sandals are very attractive and comfortable. I generally wear a size 8.5 but needed a size 10 in this brand. First full day I did end up with minor rub marks on the top of my foot but all shoes need to be broken in. Since then I have been very comfortable. After having a tumor removed from the bottom of one of my feet and enduring years of nerve pain I need good soles. These seem very well made and I am happy with the price."

"These are hands down the most comfortable sandals I’ve ever worn! They fit true to size and feel really well made. Honestly I’d sleep in them if I could 😆 Even my sensory-sensitive son tried them on (they’re way too big for him) and now he wants a pair of his own!"

"Takes a few wears to get used to the arch but it gives great arch support and becomes very comfy to walk around in. I no longer get PF pain in the summer after wearing these. I sized up for a more roomy fit. I’ve worn them for months and they look relatively new just showing how durable and functional they are. The chestnut brown is also a a great color nude for those with darker skin tones."

"LISTEN… I have worn these sandals for 3 years almost every single day and any time I know I’ll be on my feet for a while. Never go on a trip without them. They have saved me so many times. I bought them for a trip to San Diego and we walked over 8 miles up and down that zoo without a single ache! Worth every penny. I recommend them 1000x over and I’ve gifted them to my sisters and they agree. Literal foot savers. They still look new and easy to clean!"
