"Cute!"

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.
Ridge is built to match your favorite dresses without you having to sacrifice comfort for the look. A metallic buckle over the strap gives it a smart touch, and the luxurious detailing on this walking sandal doesn't come at the cost of function. The footbed has a comfortable lining that optimizes support, and a velcro strap gives you real, proper adjustment options rather than a one-size guess. It's a good way to refresh a tired summer shoe rotation with something more striking. Designed for low arches, a low heel cup adds enhanced stability while the cushioned sole promotes proper alignment and reduces fatigue, and the adjustable backstrap gives a personalized, secure fit with a stylish edge. Ridge is offered in whole sizes, fits true to size, and comes in colors that pair easily with your favorite summer dresses, shorts, or jeans. Order your normal size for these. Half size or wide feet call for sizing up, not down (a 7.5 orders as an 8). Medium width overall. The Size Chart has exact measurements if you're on the fence.
