After temporarily closing our doors, Perth Studio is finally back. To make room for what’s next, we’re clearing selected warehouse pieces.
Limited quantities remain — if “Add to Cart” is visible, the item is still available.
Most thongs are a flat piece of foam with a strap through it. By the end of a beach day your arches ache and you can feel every shell you stood on. Ruby is moulded in one piece, with the shape already in it.
Contoured footbed
The arch support is moulded into the sole rather than glued on top, so it can't flatten out or peel away.
One piece of EVA
No seams, no glue, nothing to come apart. Rinse it under the tap and it's clean.
Light enough to forget
Under 200 grams a pair. They go in the beach bag without you noticing the weight.
Grip in the wet
A textured tread underneath, so wet tiles around a pool aren't a problem.
