Just got these ONCAI flip flops and wow - the arch support is LEGIT! Walked 3 miles on the boardwalk without any foot fatigue. The yoga mat footbed feels like walking on clouds.

BUT... sizing is weird af. I'm usually a US 8 but had to size down to 7.5. Even then, the straps feel loose when I wiggle my toes. My friend with wide feet says they fit her perfectly though!

The microfiber leather straps look chic but scratch a bit at first. Pro tip: wear them around the house for a day to break them in. The rubber soles saved me from wiping out on wet pool decks multiple times - grip is insane!

Color warning: my 'cognac' pair looks more like light tan IRL. If you want that rich brown from the product photos, maybe try a darker shade.

Final verdict? 4/5 stars - would totally repurchase if they fix the sizing issues. Perfect for beach vacations but maybe not for all-day city walking.
