The Rainbow Sandals Luxury Leather Single-Layer Men's Sandal is the original — handcrafted in San Clemente, California using premium full-grain leather that molds to the unique shape of your foot over time for a truly personalised, lifetime fit. Every pair becomes uniquely yours after a few weeks of regular wear, and the quality only improves with age. Upper: Premium full-grain leather strap and footbed — breaks in to your foot's exact contour for a custom fit that no synthetic sandal can replicate Footbed: Single-layer cushioned design — slim, low-profile feel with the classic Rainbow DNA surfers have trusted since 1974 Outsole: Durable natural rubber — grips pavement, sand, wooden decks, and parking lots with confidence Construction: Handcrafted in the USA — Rainbow Sandals has been making these by hand in California for over 50 years Colourways: Available in Black/Black Sole and Natural/Wood Sizing Note: Available in sizes S (US Men's 5–7) through XXXL (US Men's 16). Rainbow recommends sizing up half a size if you're between sizes, as the leather will mold snugly to your foot during break-in. The break-in period is typically 1–2 weeks of regular wear. Care: Allow to air dry naturally after exposure to water — do not use direct heat. Condition the leather footbed and strap periodically with a natural leather conditioner to maintain suppleness and prevent cracking. Store in a cool, dry place away from prolonged sunlight.
