How should I choose my size?
Use the size guide and match the heel-to-toe measurement of your longer foot. Alva & Oro sizes follow US women's sizing; use the listed men's equivalent for comparison. The strap is designed to begin snug and can relax slightly with wear.
Will the arch feel firm at first?
It can. A contoured footbed feels different from flat footwear. Begin with shorter periods of wear and increase gradually as comfort allows. Stop use if discomfort persists.
What are delivery and returns like?
Delivery usually takes 7 to 10 days. Contact us within 30 days of delivery to request a return. Opened or used products qualify. Standard return shipping is paid by the customer unless the item arrives damaged or is not working.
The easy look of a flip flop. A shape that does more.
Ordinary flip flops are often little more than a flat slab of foam. This pair follows the foot instead, with a raised heel, visible arch contour, low toe profile, and a strap designed to stay close.
A contoured footbed gives your foot a more considered surface to meet. The snug strap helps keep the sandal with you, which can reduce the need to grip with your toes just to hold it on.
Shaped from heel to toe
Support you can see before you step in.
The profile rises beneath the arch by up to 2.2 cm, lifts slightly at the heel, and stays lower toward the toes. It is a visible difference from the flat summer sandals many feet are used to.
Footbed
Contoured and textured
Material
Specialized closed-cell foam
Strap
Snug, secure, and stretchable
Construction
Made as one continuous piece
Built as one
No glued-on strap. No separate sole layers.
The sandal is formed as a single piece. The footbed texture, patterned strap, and contoured side profile are part of the same clean, uncomplicated build.
A fit that becomes yours
The foam adapts as you wear it.
The closed-cell foam gradually molds toward your foot shape. Because the contour can feel more pronounced than a flat flip flop at first, begin with shorter periods of wear and build up as comfort allows.
A firm, shaped footbed is intentional. Stop wearing the sandals if discomfort persists.
Five easy neutrals
Support that still looks like summer.
Choose from five easy neutral colors. Each keeps the same streamlined shape and contoured construction.
Know before you order
A snug start is part of the design.
01
Match your foot length
The size guide follows US women's sizing and includes men's equivalents. Measure from heel to longest toe and use your longer foot.
02
Expect a closer strap
The strap is meant to sit snugly so the flip flop moves with your foot. It can relax slightly with regular wear.
03
Ease into the contour
Start with shorter wear periods if you are used to flat footwear, then increase your time as the shape begins to feel familiar.
