Comfortable fit, love the adjustable
"Comfortable fit, love the adjustable strap, as my heel is narrow."

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.
If you've been meaning to refresh your shoe rotation, Coral is a solid place to start, a thong-style ankle strap sandal that's already popular for its fashionable look. The soft footbed has built-in medial arch support, an ankle Velcro strap, and an elegant design, features that genuinely make Coral stand out rather than blend in as an all-inclusive slingback sandal. Adjustable straps give you a customized fit, and cushioned insoles keep your feet comfortable even during long stretches of wear. The ergonomic design genuinely helps reduce foot fatigue and discomfort, whether you're running errands, heading to work, or just out for the day. Coral is offered in whole sizes and fits true to size, giving you a secure, stylish fit that's actually built for all-day wear, not just quick outings. Order your regular size. If you're a half size or your feet run wide, size up instead of down (a 7.5 becomes an 8). Medium width. The Size Chart has exact measurements if you'd like to double check.
