Quick answer: A sandal fits when the heel sits inside the footbed and the straps hold without pressing. Our Women's Soft Flat Sandals show three adjustable hook-and-loop straps in their product photos, while our slides rely on one broad strap — here is how to get the hold right.
Sandal sizing feels easy — no toe box to misjudge — and yet a sandal that is half a step too loose announces itself with every slap of the footbed. Fit in a sandal is really about two things: where your foot sits on the footbed, and how the strap or straps hold it there. Here is how that plays out across our own range, style by style.
The adjustable one: Women's Soft Flat Sandals
Our best-selling sandal — 47 pairs ordered since January 1, 2026 — is the Women's Soft Flat Sandals ($23.99). The product page emphasizes how quick they are to get on and off, and the product photos show why the fit is so forgiving: three hook-and-loop straps — across the toes, over the instep, and around the heel — each of which can be repositioned. If your foot is narrow at the front and fuller at the instep (or the reverse), you can set each strap independently instead of hoping one width fits all.
Underneath, the page describes a footbed that follows a natural contour to reduce pressure, a sole shaped to distribute weight evenly, and a flat-to-low wedge of about 1–3 cm. Sizes run US 5 to 10.5 in Red, Blue, Gray and Ochre.
Setting hook-and-loop straps properly
General fitting advice: fasten straps so they are snug enough that the sandal moves with your foot, but loose enough to slide a finger under. Start at the heel strap — it sets where your foot sits front-to-back — then the instep, then the toe strap last and lightest. Re-check after ten minutes of walking; feet settle, and hook-and-loop exists precisely so you can adjust on the go.
The one-strap approach: slides
Slides trade adjustability for instant on-off. The Comfy Pillow Slides ($19.99) describe a broad single strap that hugs the foot for a snug fit, over a thick cushioned EVA sole. The Cloud Slides ($14.99) take the same approach and are described as designed to prevent them falling off as you walk. With one fixed strap, size choice does all the work — both styles run 5.5 to 12, so most people can fine-tune by half size.
How a sandal should sit on the footbed
Same rules for every style, and these are general guidance: your heel should land fully on the footbed, not overhang the back edge; there should be a few millimetres of footbed visible beyond your toes; and nothing should press or rub at the strap edges on a first indoor walk. A sandal that passes those three checks fresh out of the box almost always stays comfortable — and if it does not pass, an indoor try-on keeps the 30-day return option open (unworn, tags on, original packaging).

Frequently asked questions
Are the Women's Soft Flat Sandals adjustable?
Yes - the product photos show three hook-and-loop straps, across the toes, over the instep and around the heel, each of which can be repositioned. The product page highlights how quickly they go on and off.
How tight should sandal straps be?
Snug enough that the sandal moves with your foot instead of slapping, loose enough to slide a finger under the strap. Set the heel strap first, then instep, then toe - and re-check after a few minutes of walking.
How do I know if a slide fits, since it cannot be adjusted?
Size does the work: your heel should sit fully on the footbed with a few millimetres of footbed beyond your toes, and the strap should hold without pressing. Both our slide styles run from 5.5 to 12, so you can tune fit by half size.
Do the flat sandals have any lift?
A little: the product page lists a flat-to-low wedge of about 1-3 cm, with a footbed that follows a natural contour and a sole shaped to spread weight evenly across the step.
Can I return sandals that do not fit?
Yes, within 30 days of receiving them, as long as the pair is unworn and unused, with tags, in the original packaging, and you have proof of purchase. Trying sandals indoors first keeps you eligible.
