"Attractive. Comfortable. Very supportive of my troublesome arch. These will be my go to sandals this summer."

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.
Maris is for anyone who's struggled to find footwear that actually holds up through a full day of activity without sacrificing comfort somewhere along the way. Its construction supports a feminine look while keeping your arches genuinely active through whatever the day throws at them, and a polyurethane gel injected sole keeps foot agitation to a minimum while adding real durability for extended use. A medium heel cup cradles the hindfoot for stability, and polyurethane technology in the platform keeps things lightweight, durable, and soft, providing real support to medium arches with a shock-absorbing outsole underneath. At roughly 0.412 lbs a pair with a 1.2 inch heel and 3.5 inch width, this sandal offers a relaxed fit that works well across the summer and spring wardrobe. Order your typical size. Half sizes and wider feet should size up, not down (a 7.5 orders as an 8). Medium width overall. The Size Chart has the exact measurements if you're not sure.

"Attractive. Comfortable. Very supportive of my troublesome arch. These will be my go to sandals this summer."
"This particular sandal of the many I have bought from this company has little support structure, although there is a supportive arch bed. The red color is lovely. Nice sandal given the affordable price"
"I typically buy Aerothotics exclusively when shopping for new sandals or flip-flops. The high arch is necessary due to my tendency to flat-foot, which then gives me leg pain. These did not disappoint! I love the color, the style, the comfort! I've yet to buy a pair I didn't like (and I have 6 pairs!)."
"Didn’t fit, because my fest swell up and I just couldn’t get them on… Also, after I turned one strap on the right Flip Flop I noticed there was a black mark on it… Sorry… 🙁"
"Absolutely love them. They fit my feet good and are the perfect color. All of my friends give me compliments on my feet now! Buy them now, you will thank me!"
"Super cute! Firm footbed and support holds my foot in place."
