I’ve been buying summer shoes
"I’ve been buying summer shoes from you for about five years. They are the only sandals or slides that I a wear comfortably."

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.
Tera was made to actually support your feet, not just look supportive. A padded strap gives that cushioned feel against your skin right from the first wear, no break-in period needed, and a medium heel cup keeps things stable so you're not adjusting your gait to compensate. A foam-lined footbed adds real plushness underfoot, and durable polyurethane gel-injected midsole technology molds to your arch for support that holds up over time instead of packing down. Contoured arch support promotes proper alignment and cuts down on fatigue, which is exactly why customers with high arches and plantar fasciitis keep coming back to this one specifically. A memory foam cushioned toe post and soft padded inner straps round it all out into a classic flip flop that people describe as genuinely plush, not just marketed that way. Order your usual size. If you're a half size or your feet run wide, go up a full size rather than down (7.5 orders as an 8). Medium width throughout. The Size Chart has the numbers if you want to check first.

Half Sizes or Wide Width
If you wear a half size or have wider feet, size up to the next full size. Ex: If you’re a 7.5, we recommend ordering an 8.
