BIRKENSTOCK Cork Thong EVA New Style Size 36-45 Flip Flops Thong Sandals A313

Why Your Current Flip Flops Are Failing You

If you’ve ever worn a pair of cheap flip flops on a long walk, you already know the story. By the end of the day, your heels ache, your arches feel flat, and your toes are gripping the sole just to keep them on. That’s called overcompensation, and it leads to tired feet, knee strain, and even lower back pain. The problem is clear: most thong sandals prioritize style over structure, leaving your feet unsupported with every step.

Enter the BIRKENSTOCK Cork Thong EVA (Model A313). This isn’t just another flip flop—it’s a carefully engineered solution for people who refuse to sacrifice comfort for convenience. Whether you’re dashing to the beach, walking the dog, or running errands, these sandals deliver the renowned Birkenstock support in a lightweight, water-friendly package.

The Birkenstock Difference: A Footbed That Works With You

What makes the Cork Thong EVA different? It starts with the footbed. Unlike the flat, foam slabs found in typical flip flops, Birkenstock uses a contoured cork footbed that mimics the natural shape of your foot. The deep heel cup cradles your heel, the longitudinal arch support prevents your arch from collapsing, and the toe bar encourages a natural gripping motion that strengthens your feet over time.

But this isn’t the classic cork bed you might know from traditional Birkenstocks. This version combines real cork with a layer of EVA (ethylene-vinyl acetate)—a lightweight, flexible foam that absorbs shock and reduces pressure on your joints. The result? A sandal that’s softer underfoot, easier to break in, and perfect for active days.

Who Needs This Sandal?

• First-time Birkenstock buyers who want to test the brand’s famous support without committing to a full leather clog.
• People with flat feet or plantar fasciitis seeking relief from arch pain without wearing heavy orthotics.
• Travelers and beachgoers who need a sandal that can get wet, dry quickly, and still look great with shorts or a sundress.
• Anyone tired of buying flip flops that fall apart after one season.

Designed for Real Life: Features That Matter

Every detail of the Birkenstock Cork Thong EVA is built for durability and comfort. The two-strap thong design uses adjustable metal buckle straps that secure your foot without rubbing or digging in. The straps are made from synthetic leather that’s both soft and weather-resistant, so they won’t crack or fade after exposure to sun or saltwater.

The cork-EVA footbed is covered with a breathable, moisture-wicking material that keeps your feet dry and comfortable, even in warm weather. And because cork naturally absorbs shock and molds to your foot over time, these sandals get more comfortable the more you wear them.

Worried about slipping? The EVA outsole features a tread pattern that provides excellent grip on wet surfaces, from pool decks to rain-soaked sidewalks.

Available in Sizes 36-45 (US Women’s 5-11, US Men’s 4-10.5)

Getting the right fit is crucial for Birkenstocks. Unlike standard shoe sizing, Birkenstock uses European measurements. The Cork Thong EVA runs true to Birkenstock size—if you’ve worn the classic Arizona, choose the same size. If you’re new to the brand, measure your foot from heel to longest toe and compare with the brand’s size chart. A proper fit means your heel sits snugly in the cup and you have a thumb’s width of space at the toe.

How to Break In and Care for Your Birkenstock Cork Thong EVA

Even with the EVA cushioning, these sandals require a short break-in period. Wear them for 2–3 hours on the first day, then gradually increase time. Your feet will adjust to the new support, and the cork will begin to conform to your unique foot shape. If you feel any discomfort, it’s normal—your feet are learning to stand correctly.

Caring for your sandals is simple. For light cleaning, wipe the footbed with a damp cloth and mild soap. Avoid soaking the cork or exposing it to extreme heat (like leaving them in a hot car). The EVA components are water-friendly, but the cork can dry out if exposed to prolonged moisture. Spot clean as needed, and store them away from direct sunlight.

Why Choose Birkenstock Over Other Brands?

You might wonder: why spend $69.88 on flip flops when you can buy a $10 pair at the drugstore? Because your feet deserve better. According to the American Podiatric Medical Association, poorly designed footwear can contribute to long-term foot problems. Birkenstock has been crafting foot-healthy shoes for over 200 years, and their designs are backed by podiatrists and satisfied customers worldwide.

The Cork Thong EVA offers the same biomechanical benefits as the classic Birkenstock sandals—improved posture, reduced joint strain, and all-day comfort—in a convenient, lightweight thong format. Plus, the durable construction means these sandals will last for years, not just one summer.
