The Ra IV reimagines the classic Oxford through a barefoot lens – smart in appearance and uncompromising in feel and natural movement. Crafted with Wild Hide leather, organic cotton laces, and a cork insole, and sitting on a flexible 4mm Gobi outsole that keeps you connected to every step, the Ra IV is built to support strong, free feet no matter the occasion.
Product information
New Gobi Outsole
Sidestitched, not glued.
Vivos are designed with thin soles to help reconnect you with the ground, and provide flexibility for strong, healthy feet.
1.3mm
Tread depth refers to the thickness of the patterns or “lugs,” on the sole. These are purposefully designed to cater to specific surfaces and conditions, providing an ideal combination of traction, grip, and a sense of connection with the ground.
The Gobi outsole’s side-stitching can be easily disassembled once it’s lived a full life, meaning you can send your old Vivos to our Revivo service, and we’ll fix them up so you can extend your wear time and adventures.
Embrace your human nature.
The best piece of technology ever to be put in a shoe? The human foot. So let’s set it free. You’ve got everything you need, naturally.
Cork & recycled PU insole

Care instructions
Cleaning
Brush off mud and clean with a dry cloth.
Drying
Remove insole and dry at room temperature. Keep out of direct sunlight and avoid intense heat source.
Aftercare
We recommend using Renapur Leather Balsam to nourish the leather, restore the colour and finish and help prevent the leather from drying out and cracking. It’s ideal to treat new footwear as it helps relax the new leather and make your footwear waterproof.
Repair Options
Laces and insoles can be replaced. Outsoles and hardware can be replaced with our Revivo Repairs Programme.
End of life
Once you can’t repair or don’t need them anymore, send us your old Vivos and we’ll make they sure they’re given a second life, or if they’re really well-loved, we’ll store them until we launch our recycling solution.
