My slip ons are supportive
"My slip ons are supportive , comfortable but also stylish. I love the square back."

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.
Most sandals look good on a shelf and punish you after an hour. Otis flips that. A contoured polyurethane footbed wraps your arch before the first step, a non-slip outsole locks you in on any surface, and a signature gold buckle keeps the look sharp whether you're at the beach or running errands. Light enough to travel with, supportive enough to wear all day. Otis is the sandal you reach for without thinking twice. Accepted by the American Podiatric Medical Association.
