I love these slippers! They
"I love these slippers! They are the most comfortable slippers I have ever bought, they are warm and no one hears me walking."

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.

"I have neuropathy and these are very soft"
"Soft supportive and the best slippers I have ever owned"
"I’ve been an Aerothotic fan for a while, but these winter sandals blew me away. The fuzzy material is so soft, and the arch support is still as amazing as ever. I couldn’t believe they dropped a winter line, so I ordered two pairs from Amazon a week before without hesitation."
"These are perfect for winter lounging! The fuzzy feel and slide style are so comfy, and the arch support is amazing. I was really shocked to find winter sandals from Aerothotic but they made the best decision! It was really needed."
"I’m honestly shocked that Aerothotic has winter sandals now! They’re soft, warm, and offer the same incredible arch support as their summer styles. I’ve already ordered multiple pairs—these are a must-have!"
"I love love love them --- thanks"
"The cozy feel combined with their signature arch support is the BEST!!! Though I ordered a few pairs off Amazon right away, and they’ve been perfect for chilly days indoors and outdoors both."
